Its annihilation into hadronic final states produces a challenging zoo of light hadronic resonances. We update Herwig7 to study the photon and positron spectra from annihilation through a vector mediator. It covers dark matter masses between 250 MeV and 5 GeV and includes an error estimate. \\ ( https://arxiv.org/abs/1911.11147 , 930kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11213 Date: Mon, 25 Nov 2019 20:27:40 GMT (81kb,D) Title: $\Delta(1232)$ Contribution in the $\pi$-photoproduction on Nucleons in Covariant Chiral Perturbation Theory Authors: Gustavo H. Guerrero Navarro Categories: hep-ph Comments: Conference proceedings of the XVIII International Conference on Hadron Spectroscopy and Structure, HADRON 2019. August 16-21, Guilin, China \\ We study the effects of the $\Delta$(1232) resonance as an effective degree of freedom for charged and neutral pion photo-production on nucleons. Different observables have been calculated for these processes by using relativistic chiral perturbation theory up to $\mathcal{O}(p^3)$ in the $ \delta$ counting, thus, including pion loops. We compare our model with a large database containing the available experimental data and constrain some unknown low energy constants. \\ ( https://arxiv.org/abs/1911.11213 , 81kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11235 Date: Mon, 25 Nov 2019 21:14:20 GMT (1427kb,D) Title: The Time Substructure of Jets and Boosted Object Tagging Authors: Matthew D. Klimek Categories: hep-ph hep-ex Comments: 8 pages + references \\ We initiate the study of the time substructure of jets, motivated by the fact that the next generation of detectors at particle colliders will resolve the time scale over which jet constituents arrive. This effect is directly related to hadronization, which transforms partons into massive hadrons with a distribution of velocities. We review the basic predictions for the velocity distribution of jet hadrons, and suggest an application for this information in the context of boosted object tagging. By noting that the velocity distribution is determined by the properties of the color string which ends on the parton that initiates the jet, we observe that jets originating from boosted color singlets, such as Standard Model electroweak bosons, will exhibit velocity distributions that are boosted relative to QCD jets of similar jet energy. We find that by performing a simple cut on the corresponding distribution of charged hadron arrival times at the detector, we can discriminate against QCD jets that would otherwise give a false positive under a traditional spatial substructure based boosted object tagger. \\ ( https://arxiv.org/abs/1911.11235 , 1427kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11244 Date: Mon, 25 Nov 2019 21:39:13 GMT (475kb,D) Title: Electroweak Loops as a Probe of New Physics in $t\bar{t}$ Production at the LHC Authors: Till Martini and Markus Schulze Categories: hep-ph hep-ex Comments: 12 pages, 7 figures Report-no: HU-EP-19/36 \\ We calculate the $\mathcal{O}(\alpha)$ weak corrections to top quark pair production at the LHC and include anomalous electroweak interactions from dimension-six operators. The loop calculation and renormalization are consistently done within the Standard Model Effective Field Theory. Sensitivity to the involved operators is exposed through the virtual corrections, which receive enhancement from electroweak Sudakov logarithms. We investigate the prospects of using this feature for probing New Physics at the LHC that so far has only been studied in final states with on-shell sensitivity such as $t\bar{t}+Z$ or $t \to b W$. We find that the large $t\bar{t}$ production rate and the excellent perturbative control allow compensating the loop suppression and yield remarkably strong constraints that are competitive with those from $t\bar{t}+Z$. \\ ( https://arxiv.org/abs/1911.11244 , 475kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11254 Date: Mon, 25 Nov 2019 22:03:34 GMT (556kb,D) Title: Dark Matter Freeze Out with Tsallis Statistics in the Early Universe Authors: Thomas D. Rueter, Thomas G. Rizzo, JoAnne L. Hewett Categories: hep-ph Comments: 19 pages, 9 figures \\ The nature of dark matter (DM) and how it might interact with the particles of the Standard Model (SM) is one of greatest mysteries currently facing particle physics, and addressing these issues should provide some understanding of how the observed relic abundance was produced. One widely considered production mechanism, a weakly interacting massive particle (WIMP) produced as a thermal relic, provides a target cross section for DM annihilation into SM particles by solving the Boltzmann equation. In this thermal freeze-out mechanism, dark matter is produced in thermal equilibrium with the SM in the early universe, and drops out of equilibrium to its observed abundance as the universe cools and expands. In this paper, we study the impact of a generalized thermodynamics, known as Tsallis statistics and governed by a parameter $q$, on the target DM annihilation cross section. We derive the phase space distributions of particles in this generalized statistical framework, and check their thermodynamic consistency, as well as analyzing the impact of this generalization on the collisional term of the Boltzmann equation. We consider the case of an initial value of $q_0>1$, with $q$ relaxing to 1 as the universe expands and cools, and solve the generalized Boltzmann numerically for several benchmark DM masses, finding the corresponding target annihilation cross sections as a function of $q_0$. We find that as $q$ departs from the standard thermodynamic case of $q=1$, the collisional term falls less slowly as a function of $x = m_\chi/T$ than expected in the standard case. We also find that the target cross section falls sharply from $\sigma v \simeq 2.2-2.6\times10^{-26} \textrm{cm}^3/\textrm{s}$ for $q_0=1$ to, for example, $\sigma v \simeq 3\times 10^{-34} \textrm{cm}^3/\textrm{s}$ for $q_0=1.05$ for a 100 GeV WIMP. \\ ( https://arxiv.org/abs/1911.11254 , 556kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11346 Date: Tue, 26 Nov 2019 05:14:54 GMT (8248kb,D) Title: Extending the reach of FASER, MATHUSLA and SHiP towards smaller lifetimes using secondary production Authors: Krzysztof Jod{\l}owski, Felix Kling, Leszek Roszkowski, Sebastian Trojanowski Categories: hep-ph Comments: 32 pages, 13 figures \\ Many existing or proposed intensity-frontier search experiments look for decay signatures of light long-lived particles (LLPs), highly displaced from the interaction point, in a distant detector that is well-shielded from SM background. This approach is, however, limited to new particles with decay lengths similar or larger than the baseline of those experiment. In this study, we discuss how this basic constraint can be overcome in BSM models that go beyond the simplest scenarios. If more than one light new particle is present in the model, an additional secondary production of LLPs may take place right in front of the detector, opening this way a new lifetime regime to be probed. We illustrate the prospects of such searches in the future experiments FASER, MATHUSLA and SHiP, for representative models, emphasizing possible connections to dark matter or anomalous magnetic moment of muon. We also analyze additional advantages from employing dedicated neutrino detectors placed in front of the main decay volume. \\ ( https://arxiv.org/abs/1911.11346 , 8248kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11369 Date: Tue, 26 Nov 2019 06:51:01 GMT (7kb) Title: The effect of radiation corrections to the mass of an electron and positron on the polarization operator of a photon in a magnetic field Authors: V.M. Katkov Categories: hep-ph \\ The polarization operator of a photon in a constant and uniform magnetic field is studied taking into account the radiation width and shift of the Landau levels in both weak and strong fields compared with the critical field $H_0=4,41\cdot10^{13}$ G . A general formula is obtained for the polarization operator of a photon in which radiation effects are taken into account. Now diverging previously threshold terms have a finite value. The conditions are formulated under which the energy levels completely overlap, and thereby the most appropriate application of the semiclassical operator method to the problem under study becomes. \\ ( https://arxiv.org/abs/1911.11369 , 7kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11383 Date: Tue, 26 Nov 2019 07:50:26 GMT (84kb,D) Title: The decay $\tau \to K^{*-}(892) \eta \nu_{\tau}$ in the NJL model Authors: M. K. Volkov, A. A. Pivovarov and K. Nurlan Categories: hep-ph Comments: 4 pages, 3 figures \\ The decay width $\tau \to K^{*-}(892) \eta \nu_{\tau}$ was calculated in the Nambu--Jona-Lasinio model. Four channels were taken into account: the contact channel (the final states are directly producted from lepton current without any intermediate meson states), the axial-vector channel with two intermediate physical states $K_{1}(1270)$ and $K_{1}(1400)$, the vector channel with intermediate $K^{*}(892)$ meson and the pseudoscalar channel with intermediate $K$ meson. It is shown that the first two channels give the dominant contribution to the decay width. Of the remaining two channels, the pseudoscalar channel plays a more prominent role. The final result is in satisfactory agreement with experimental data. Prediction for the differential decay width is presented. \\ ( https://arxiv.org/abs/1911.11383 , 84kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11411 Date: Tue, 26 Nov 2019 09:08:20 GMT (2154kb,D) Title: Threshold effects in SO(10) models with one intermediate breaking scale Authors: Davide Meloni, Tommy Ohlsson, Marcus Pernow Categories: hep-ph Comments: 34 pages, 3 figures, 8 tables \\ Despite the successes of the Standard Model of particle physics, it is known to suffer from a number of deficiencies. Several of these can be addressed within non-supersymmetric theories of grand unification based on $\text{SO}(10)$. However, achieving gauge coupling unification in such theories is known to require additional physics below the unification scale, such as symmetry breaking in multiple steps. Many such models are disfavored due to bounds on the proton lifetime. Corrections arising from threshold effects can, however, modify these conclusions. We analyze all seven relevant breaking chains with one intermediate symmetry breaking scale. Two are allowed by proton lifetime and two are disfavored by a failure to unify the gauge couplings. The remaining three unify at a too low scale, but can be salvaged by various amounts of threshold corrections. We parametrize this and thereby rank the models by the size of the threshold corrections required to save them. \\ ( https://arxiv.org/abs/1911.11411 , 2154kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11507 Date: Tue, 26 Nov 2019 13:13:07 GMT (224kb,D) Title: Leading two-loop corrections to the Higgs boson self-couplings in models with extended scalar sectors Authors: Johannes Braathen and Shinya Kanemura Categories: hep-ph Comments: 68 pages, 10 figures Report-no: OU-HET-1030 \\ We compute the dominant two-loop corrections to the Higgs trilinear coupling $\lambda_{hhh}$ and to the Higgs quartic coupling $\lambda_{hhhh}$ in models with extended Higgs sectors, using the effective-potential approximation. We provide in this paper all necessary details about our calculations, and present general $\overline{\text{MS}}$ expressions for derivatives of the integrals appearing in the effective potential at two loops. We also consider three particular Beyond-the-Standard-Model (BSM) scenarios -- namely a typical scenario of an Inert Doublet Model (IDM), and scenarios of a Two-Higgs-Doublet Model (2HDM) and of a Higgs Singlet Model (HSM) without scalar mixing -- and we include all the necessary finite counterterms to obtain (in addition to $\overline{\text{MS}}$ results) on-shell scheme expressions for the corrections to the Higgs self-couplings. With these analytic results, we investigate the possible magnitude of two-loop BSM contributions to the Higgs self-couplings and the fate of the non-decoupling effects that are known to appear at one loop. We find that, at least as long as pertubative unitarity conditions are fulfilled, the size of two-loop corrections remains well below that of one-loop corrections. Typically, two-loop contributions to $\lambda_{hhh}$ amount to approximately 20\% of those at one loop, implying that the non-decoupling effects observed at one loop are not significantly modified, but also meaning that higher-order corrections need to be taken into account for the future perspective of precise measurements of the Higgs trilinear coupling. \\ ( https://arxiv.org/abs/1911.11507 , 224kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11524 Date: Tue, 26 Nov 2019 13:34:33 GMT (56kb,AD) Title: Higgs decay into massive b-quarks at NNLO QCD in the nested soft-collinear subtraction scheme Authors: Arnd Behring, Wojciech Bizon Categories: hep-ph Report-no: P3H-19-047, TTP19-041 \\ We present a fully differential description of a decay of a scalar Higgs boson into massive b-quarks valid at next-to-next-to-leading order (NNLO) in perturbative quantum chromodynamics (QCD).

Especially, the contributions of tensor operators have been calculated for the first time in this work. Since the lepton mass is retained in our calculations, the lepton flavour universality and the decay mode $\Lambda_b \to \Lambda(\to N \pi) \tau^+\tau^-$ can be studied in detail. For comparison with the experiment, we study the numerical results of observables within the Standard Model and the $S_1+S_3$ Leptoquark model. Significant deviation can be found between experiment data and the Standard Model predictions. The $S_1+S_3$ Leptoquark model can be further explored with the experimental progresses. In addition, we demonstrate the sensitivity of various angular observables to tensor operators contributions firstly, and find out that the potential New Physics effects of tensor operators can not be ignored in $b\to s\ell^+\ell^-$ transitions. \\ ( https://arxiv.org/abs/1911.11568 , 972kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11630 Date: Mon, 25 Nov 2019 11:01:38 GMT (92kb,D) Title: The three-loop polarized pure singlet operator matrix element with two different masses Authors: J.

The behavior of the DIS reduced cross section studied and compared with the experimental data, also these behaviors controlled by the nonlinear and higer twist corrections at low $Q^{2}$. These results were augmented by including an additional higher-twist term in the description of the nonlinear correction. This additional term, modified nonlinear correction, improves the description of the reduced cross sections significantly at low values of $Q^{2}$. Our calculations show a good agreement with the DIS experimental data throughout the low values of $x$. We discuss, furthermore, how this behavior can be determine the reduced cross section with respect to the proton parameterization at high-y values. These results within the next-to-next-to-leading order approximation at very low $x$ can be applied in the LHeC and FCC-eh regions for analyses of ultra-high energy processes. The resulting predictions for $\sigma_{r}$ suggest that further corrections are required for $Q^{2}$ less than about $3~\mathrm{GeV}^{2}$. \\ ( https://arxiv.org/abs/1911.11635 , 263kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11677 Date: Tue, 26 Nov 2019 16:22:59 GMT (1523kb,D) Title: Strong dynamics and dark matter: investigating a minimal setup Authors: Benjamin Fuks, Federica Giacchino, Laura Lopez-Honorez, Michel H.G.

Such a model can be seen as a simplified version of a composite setup in which the scalar field, that couples to the top quark via a Yukawa interaction with the new heavy quark, is a viable dark matter candidate. We emphasize that QCD corrections are important not only for predictions at colliders but also for direct and indirect dark matter searches and the relic abundance.

Just below the $\gamma p$ threshold, the cross section is dominated by the mean field contribution of nucleons inside the nucleus. The SRC contributions start to dominate at lower photon energies, depending on the fraction of the SRC pairs in the target nucleus.

The one-loop amplitudes are obtained for all possible configurations of pion masses. The second iteration is presented in detail in the cases where either all masses of charged and neutral pions are equal, or for the decay into three neutral pions. Issues related to analyticity properties of the amplitudes and of their lowest partial-wave projections are given particular attention. This study is introduced by a brief survey of the situation, for both experimental and theoretical aspects, of the decay modes into three pions of charged and neutral kaons and of the eta meson. \\ ( https://arxiv.org/abs/1911.11762 , 2788kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11765 Date: Tue, 26 Nov 2019 18:59:33 GMT (836kb,D) Title: The Left-Right Symmetric Composite Higgs Authors: Cong-Sen Guan, Teng Ma, Jing Shu Categories: hep-ph hep-th Comments: 10 pages, 3 figures \\ We find the exchange symmetry between left and right handed top quark in composite Higgs model with partial compositeness is efficient to soften the Higgs potential and reduce fine tuning. This symmetry can keep the Higgs potential in top sector invariant under trigonometric parity $\sin (h/f) \leftrightarrow \cos (h/f)$ and thus the Higgs quadratic divergences can be completely cancelled, resulting a UV insensitive Higgs potential. We explicitly construct the minimal left-right symmetric model based on coset space $SO(6)/SO(5)$ which is locally isomorphic to $SU(4)/Sp(4)$ and thus has well defined fermionic UV completion. This UV completion can automatically keep Higgs potential in gauge sector finite even the gauge sector breaks this discrete symmetry. We find that the vector mesons can be very heavy while the colored top partners are relatively light ($>1.5$ TeV) to obtain a light Higgs. \\ ( https://arxiv.org/abs/1911.11765 , 836kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1911.11144 (*cross-listing*) Date: Mon, 25 Nov 2019 19:00:00 GMT (1502kb,D) Title: Probing the Small-Scale Matter Power Spectrum with Large-Scale 21-cm Data Authors: Julian B. Mu\~noz, Cora Dvorkin, and Francis-Yan Cyr-Racine Categories: astro-ph.CO hep-ph Comments: 23 pages, 17 figures. Comments are welcome \\ The distribution of matter fluctuations in our universe is key for understanding the nature of dark matter and the physics of the early cosmos. Different observables have been able to map this distribution at large scales, corresponding to wavenumbers $k\lesssim 10$ Mpc$^{-1}$, but smaller scales remain much less constrained. The 21-cm line is a promising tracer of early stellar formation, which took place in small haloes (with masses $M\sim 10^6-10^8M_\odot$), formed out of matter overdensities with wavenumbers as large as $k\approx100$ Mpc$^{-1}$. Here we forecast how well both the 21-cm global signal, and its fluctuations, could probe the matter power spectrum during cosmic dawn ($z=12-25$). We find that the long-wavelength modes (with $k\lesssim40$ Mpc$^{-1}$) are highly degenerate with astrophysical parameters, whereas the modes with $k= (40-80)$ Mpc$^{-1}$ are more readily observable. This is further illustrated in terms of the principal components of the matter power spectrum, which peak at $k\sim 50$ Mpc$^{-1}$ both for a typical experiment measuring the 21-cm global signal and its fluctuations. We find that, imposing broad priors on astrophysical parameters, a global-signal experiment can measure the amplitude of the matter power spectrum integrated over $k= (40-80)$ Mpc$^{-1}$ with a precision of tens of percent. A fluctuation experiment, on the other hand, can constrain the power spectrum to a similar accuracy over both the $k=(40-60)$ Mpc$^{-1}$ and $(60-80)$ Mpc$^{-1}$ ranges even without astrophysical priors. The constraints outlined in this work would be able to test the behavior of dark matter at the smallest scales yet measured, for instance probing warm-dark matter masses up to $m_{\rm WDM}=8$ keV for the global signal and $14$ keV for the 21-cm fluctuations. This could shed light on the nature of dark matter beyond the reach of other cosmic probes. \\ ( https://arxiv.org/abs/1911.11144 , 1502kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11148 (*cross-listing*) Date: Mon, 25 Nov 2019 19:00:03 GMT (189kb,D) Title: Probing the Weak Gravity Conjecture in the Cosmic Microwave Background Authors: Martin Wolfgang Winkler, Martina Gerbino, Micol Benetti Categories: astro-ph.CO hep-ph hep-th Comments: 29 pages, 7 figures \\ The weak gravity conjecture imposes severe constraints on natural inflation. A trans-Planckian axion decay constant can only be realized if the potential exhibits an additional (subdominant) modulation with sub-Planckian periodicity. The resulting wiggles in the axion potential generate a characteristic modulation in the scalar power spectrum of inflation which is logarithmic in the angular scale. The compatibility of this modulation is tested against the most recent Cosmic Microwave Background (CMB) data by Planck and BICEP/Keck. Intriguingly, we find that the modulation completely resolves the tension of natural inflation with the CMB. A Bayesian model comparison reveals that natural inflation with modulations describes all existing data equally well as the cosmological standard model $\Lambda$CDM. In addition, the bound of a tensor-to-scalar ratio r > 0.002 correlated with a striking small-scale suppression of the scalar power spectrum occurs. Future CMB experiments could directly probe the modulation through their improved sensitivity to smaller angular scales and possibly the measurement of spectral distortions. They could, thus, verify a key prediction of the weak gravity conjecture and provide dramatic new insights into the theory of quantum gravity. \\ ( https://arxiv.org/abs/1911.11148 , 189kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11150 (*cross-listing*) Date: Mon, 25 Nov 2019 19:00:07 GMT (2585kb,D) Title: Early Structure Formation Constraints on the Ultra-Light Axion in the Post-Inflation Scenario Authors: Vid Ir\v{s}i\v{c}, Huangyu Xiao, Matthew McQuinn Categories: astro-ph.CO astro-ph.GA hep-ph hep-th Comments: 15 pages, 8 figures \\ Many works have concentrated on the observable signatures of the dark matter being an ultralight axion-like particle (ALP). We concentrate on a particularly dramatic signature in the late-time cosmological matter power spectrum that occurs if the symmetry breaking that establishes the ALP happens after inflation -- white-noise density fluctuations that dominate at small scales over the adiabatic fluctuations from inflation. These fluctuations alter the early history of nonlinear structure formation. We find that for symmetry breaking scales of $f_A \sim 10^{13}-10^{15}$GeV, which requires a high effective maximum temperature after inflation, ALP dark matter with particle mass of $m_A \sim 10^{-13}-10^{-20}$eV could significantly change the number of high-redshift dwarf galaxies, the reionization history, and the Ly$\alpha$ forest. We consider all three observables. We find that the Ly$\alpha$ forest is the most constraining of current observables, excluding $f_A \gtrsim 10^{15}$GeV ($m_A \lesssim 10^{-17}$eV) in the simplest model for the ALP and considerably lower values in models coupled to a hidden strongly interacting sector ($f_A \gtrsim 10^{13}$GeV and $m_A \lesssim 10^{-13}$eV). Observations that constrain the extremely high-redshift tail of reionization may disfavor similar levels of isocurvature fluctuations as the forest. Future $z\sim 20-30$ 21cm observations have the potential to improve these constraints further using that the supersonic motions of the isocurvature-enhanced abundance of $\sim10^4M_\odot$ halos would shock heat the baryons, sourcing large BAO features. \\ ( https://arxiv.org/abs/1911.11150 , 2585kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11168 (*cross-listing*) Date: Mon, 25 Nov 2019 19:06:06 GMT (809kb,D) Title: Asymptotic safety with Majorana fermions and new large N equivalences Authors: Andrew D.

Results include a triality of asymptotically safe theories and dualities between asymptotically free matter-gauge theories with identical fixed points, phase diagrams, and scaling exponents.

Pionless effective field theory with dibaryon fields is used to calculate the total cross sections for the neutrino energies $E_\nu$ from threshold to 20 MeV. Amplitudes are expanded up to next-to-leading order, and the partial wave is truncated at P-waves. Coulomb interaction between two protons is included non-perturbatively in the reaction amplitudes, and an analytic expression of the amplitudes is obtained. Contribution of the next-to-leading order to the total cross section is in the range of 5.2$\sim$9.9\% in magnitude, and that of P-wave is 2.4$\sim$2.8\% at $E_\nu = 20$ MeV. Uncertainty arising from an axial isovector low-energy constant is estimated at the order of 1\%. \\ ( https://arxiv.org/abs/1911.11307 , 49kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11439 (*cross-listing*) Date: Tue, 26 Nov 2019 10:24:14 GMT (592kb) Title: Phase structure of the 1+1 dimensional Nambu--Jona-Lasinio model with isospin Authors: Michael Thies Categories: hep-th hep-lat hep-ph Comments: 14 pages, 8 figures; \\ The phase diagram of the two-dimensional Nambu--Jona-Lasinio model with isospin is explored in the large Nc limit with semiclassical methods. We consider finite temperature and include chemical potentials for all conserved charges. In the chiral limit, a full analytical solution is presented, expressed in terms of known results for the single-flavor Gross-Neveu and Nambu--Jona-Lasinio models. A novel crystalline structure appears and is shown explicitly to be thermodynamically more stable than the homogeneous phase at zero temperature. If we include a bare fermion mass, the problem reduces again to solved problems in one-flavor models provided that either the fermionic or the isospin chemical potentials vanish. In the general case, a stability analysis is used to construct the perturbative phase boundary between homogeneous and inhomogeneous phases. This is sufficient to get a good overview of the complete phase diagram. Missing non-perturbative phase boundaries requiring a full numerical Hartree-Fock calculation will be presented in future work. \\ ( https://arxiv.org/abs/1911.11439 , 592kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11465 (*cross-listing*) Date: Tue, 26 Nov 2019 11:37:32 GMT (968kb,D) Title: Partial deconfinement in gauge theories Authors: Masanori Hanada, Goro Ishiki and Hiromasa Watanabe Categories: hep-lat hep-ph hep-th Comments: 7 pages, 8 figures, talk presented at the 37th International Symposium on Lattice Field Theory (Lattice 2019), 16-22 June 2019, Wuhan, China Report-no: UTHEP-739 \\ We provide the evidence for the existence of partially deconfined phase in large-$N$ gauge theory. In this phase, the SU($M$) subgroup of SU($N$) gauge group deconfines, where $\frac{M}{N}$ changes continuously from zero (confined phase) to one (deconfined phase).

The couplings considered give rise to two distinct sources of entropy perturbations that may not be suppressed in the long wavelength limit. The first is merely induced by the presence of more than one scalar and arises even in the minimal coupling limit. The second source however is restricted to nonminimal interaction. Unlike the case of metric gravity, and due to the absence of anisotropic stresses, the second source disappears for single scalar, showing that nonminimal couplings become relevant to non-adiabatic perturbations only when more than one scalar field are considered. Hence the notion of adiabaticity is not affected by the transition to minimal coupling contrary to the metric gravity case where it becomes frame-dependent. Precise data that might be able to neatly track different sources of isocurvature modes, if any, must not only distinguish between different models of inflation but also determine the most viable approach to gravity which underlies the inflationary dynamics itself. \\ ( https://arxiv.org/abs/1911.11495 , 23kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11513 (*cross-listing*) Date: Tue, 26 Nov 2019 13:21:33 GMT (977kb,D) Title: Reheating in $R^2$ Palatini inflationary models Authors: Ioannis D. Gialamas and A. B. Lahanas Categories: gr-qc astro-ph.CO hep-ph Comments: 34 pages, 12 figures, pdflatex \\ We consider $R^2$ inflation in the Palatini gravity assuming the existence of scalar fields, coupled to gravity in the most general manner. These theories, in the Einstein frame, and for one scalar field $h$, share common features with $K$ - inflation models. We apply this formalism for the study of popular inflationary models, whose potentials are monomials, $ V \sim h^{n} $, with $ n $ a positive even integer. We also study the Higgs model non-minimally coupled to gravity. Although these have been recently studied, in the framework of the Palatini approach, we show that the scalar power spectrum severely constrains these models. Although we do not propose a particular reheating mechanism, we show that the quadratic $ \sim h^2$ and the Higgs model can survive these constraints with a maximum reheating temperature as large as $ \sim 10^{15} \, GeV$, when reheating is instantaneous. However, this can be only attained at the cost of a delicate fine-tuning of couplings. Deviations from this fine-tuned values can still yield predictions compatible with the cosmological data, for couplings that lie in very tight range, giving lower reheating temperatures. \\ ( https://arxiv.org/abs/1911.11513 , 977kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11531 (*cross-listing*) Date: Tue, 26 Nov 2019 13:50:17 GMT (1915kb,D) Title: Continuous $\beta$ function for the SU(3) gauge systems with two and twelve fundamental flavors Authors: Anna Hasenfratz and Oliver Witzel Categories: hep-lat hep-ph hep-th Comments: Contribution to 37th International Symposium on Lattice Field Theory - Lattice2019 16-22 June 2019, Wuhan, China \\ The gradient flow transformation can be interpreted as continuous real-space renormalization group transformation if a coarse-graining step is incorporated as part of calculating expectation values. The method allows to predict critical properties of strongly coupled systems including the renormalization group $\beta$ function and anomalous dimensions at nonperturbative fixed points. In this contribution we discuss a new analysis of the continuous renormalization group $\beta$ function for $N_f=2$ and $N_f=12$ fundamental flavors in SU(3) gauge theories based on this method. We follow the approach developed and tested for the $N_f=2$ system in arXiv:1910.06408. Here we present further information on the analysis, emphasizing the robustness and intuitive features of the continuous $\beta$ function calculation. We also discuss the applicability of the continuous $\beta$ function calculation in conformal systems, extending the possible phase diagram to include a 4-fermion interaction. The numerical analysis for $N_f=12$ uses the same set of ensembles that was generated and analyzed for the step scaling function in arXiv:1909.05842. The new analysis uses volumes with $L \ge 20$ and determines the $\beta$ function in the $c=0$ gradient flow renormalization scheme. The continuous $\beta$ function predicts the existence of a conformal fixed point and is consistent between different operators. Although determinations of the step scaling and continuous $\beta$ function use different renormalization schemes, they both predict the existence of a conformal fixed point around $g^2\sim 6$. \\ ( https://arxiv.org/abs/1911.11531 , 1915kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11575 (*cross-listing*) Date: Tue, 26 Nov 2019 14:41:57 GMT (351kb,D) Title: Study of thermal SU(3) supersymmetric Yang-Mills theory and near-conformal theories from the gradient flow Authors: Georg Bergner, Camilo L\'opez and Stefano Piemonte Categories: hep-lat hep-ph hep-th Comments: 7 pages, 3 figures, talk given at the 37th International Symposium on Lattice Field Theory - Lattice2019,16-22 June 2019, Wuhan, China \\ We compute the renormalization group flow of the mass anomalous dimension in adjoint QCD with $N_{f}=1$, $3/2$, and 2 Dirac fermions, using the gradient flow. Preliminary results are in agreement with at least a near-conformal scenario in all cases. At the largest flavor numbers we obtain the strongest indication for an IR conformal fixed point scenario. Moreover, we provide results for the thermal phase transitions in SU(3) supersymmetric Yang-Mills theory. We find hints for a connection between chiral and center symmetries in terms of a single first order phase transition where chiral symmetry is restored and center symmetry gets broken. \\ ( https://arxiv.org/abs/1911.11575 , 351kb) ------------------------------------------------------------------------------ \\ arXiv:1911.11676 (*cross-listing*) Date: Tue, 26 Nov 2019 16:19:57 GMT (344kb,D) Title: Parton Distribution Functions of Heavy Mesons on the Light Front Authors: Jiangshan Lan, Chandan Mondal, Meijian Li, Yang Li, Shuo Tang, Xingbo Zhao and James P.

Early dark energy models suffer from a coincidence problem---the physics of matter-radiation equality and early dark energy are completely disconnected, so some degree of fine-tuning is needed in order for them to occur nearly simultaneously. In this paper we propose a natural explanation for this coincidence. If the early dark energy scalar couples to neutrinos then it receives a large injection of energy around the time that neutrinos become non-relativistic. This is precisely when their temperature is of order their mass, which, coincidentally, occurs around the time of matter-radiation equality. Neutrino decoupling therefore provides a natural trigger for early dark energy by displacing the field from its minimum just before matter-radiation equality. We discuss various theoretical aspects of this proposal, potential observational signatures, and future directions for its study. \\ ( https://arxiv.org/abs/1911.11760 , 89kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1612.07855 (*cross-listing*) replaced with revised version Mon, 25 Nov 2019 19:00:09 GMT (525kb,D) Title: Testing parity-violating physics from cosmic rotation power reconstruction Authors: Toshiya Namikawa (Stanford, SLAC) Categories: astro-ph.CO hep-ph hep-th Comments: 10 pages, 6 figures, minor typo corrected DOI: 10.1103/PhysRevD.95.043523 \\ ( https://arxiv.org/abs/1612.07855 , 525kb) ------------------------------------------------------------------------------ \\ arXiv:1811.07265 replaced with revised version Tue, 26 Nov 2019 15:44:42 GMT (954kb) Title: A diagrammatic analysis of two-body charmed baryon decays with flavor symmetry Authors: H.J.
