Authors: Christian Gross, Antonello Polosa, Alessandro Strumia, Alfredo Urbano, Wei Xue Categories: hep-ph astro-ph.CO Comments: 31 pages, 11 figures \\ We critically reexamine two possible Dark Matter candidate within the Standard Model. First, we consider the $uuddss$ exa-quark. Its QCD binding energy could be large enough to make it (quasi) stable. We show that the cosmological Dark Matter abundance is reproduced thermally if its mass is 1.2 GeV. However, we also find that such mass is excluded by the stability of Oxygen nuclei. Second, we consider the possibility that the instability in the Higgs potential leads to the formation of primordial black holes while avoiding vacuum decay during inflation. We show that the non-minimal Higgs coupling to gravity must be as small as allowed by quantum corrections, $|\xi_H| < 0.01$. Even so, one must assume that the Universe survived in $e^{120}$ independent regions to fluctuations that lead to vacuum decay with probability 1/2 each. \\ ( https://arxiv.org/abs/1803.10242 , 1349kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10247 Date: Tue, 27 Mar 2018 18:00:17 GMT (83kb,D) Title: Zooming in on neutrino oscillations with DUNE Authors: Rahul Srivastava, Christoph A. Ternes, Mariam T\'ortola, Jos\'e W. F. Valle Categories: hep-ph hep-ex Comments: 20 pages, 8 figures Report-no: IFIC/18-xxx \\ We examine the capabilities of the DUNE experiment as a probe of the neutrino mixing paradigm. Taking the current status of neutrino oscillations and the design specifications of DUNE, we determine the experiment's potential to probe the structure of neutrino mixing and CP violation. We focus on the poorly determined parameters $\theta_{23}$ and $\delta_{CP}$ and consider both two and seven years of run. We take various benchmarks as our true values, such as the current preferred values of $\theta_{23}$ and $\delta_{CP}$, as well as several theory-motivated choices. We determine quantitatively DUNE's potential to perform a precision measurement of $\theta_{23}$, as well as to test the CP violation hypothesis in a model-independent way. We find that, after running for seven years, DUNE will make a substantial step in the precise determination of these parameters, bringing to quantitative test the predictions of various theories of neutrino mixing. \\ ( https://arxiv.org/abs/1803.10247 , 83kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10248 Date: Tue, 27 Mar 2018 18:00:18 GMT (52kb,D) Title: $Z$ boson production in bottom-quark fusion: a study of $b$-mass effects beyond leading order Authors: Stefano Forte, Davide Napoletano, Maria Ubiali Categories: hep-ph hep-ex Comments: 14 pages, 3 figures \\ We compute the total cross-section for $Z$ boson production in bottom-quark fusion, applying to this case the method we previously used for Higgs production in bottom fusion. Namely, we match, through the FONLL procedure, the next-to-next-to-leading-log five-flavor scheme result, in which the $b$~quark is treated as a massless parton, with the next-to-leading-order $\order{\alpha_s^3}$ four-flavor scheme computation in which bottom is treated as a massive final-state particle. Our computation provides a test-case for the discussion of issues of scale dependence and treatment of heavy quarks, which we discuss in light of our results. \\ ( https://arxiv.org/abs/1803.10248 , 52kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10379 Date: Wed, 28 Mar 2018 01:40:18 GMT (7344kb,D) Title: Les Houches 2017: Physics at TeV Colliders New Physics Working Group Report Authors: G.

These radiative corrections couple the different strongly interacting Dyson equations. We discuss how the boundary conditions of the coupled SDE system are modified by these corrections, and verify that the ultraviolet behavior of the self-energies are described by a function that decreases logarithmically with momentum. \\ ( https://arxiv.org/abs/1803.10458 , 118kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10466 Date: Wed, 28 Mar 2018 08:51:44 GMT (343kb) Title: Z Polarization in $e^+e^-\to t\bar t Z$ for testing the top quark mass structure and the presence of final interactions Authors: Fernand M Renard Categories: hep-ph Comments: 10 pages, 4 figures \\ We show that the measurement of the $Z$ polarization in the $e^+e^-\to t\bar t Z$ process would allow an interesting determination of the role of the top quark mass.

Taking account of the event selection conditions, it is shown that the ILC is sensitive to smaller LFV couplings as compared to the measurement of $\tau\to 3e$ process at the B-factory experiment. The upper bounds on some of the LFV couplings are improved by several factors using polarized $e^-/e^+$ beams at $\sqrt{s}=250~\mathrm{GeV}$ and by an order of magnitude at $\sqrt{s}=1~\mathrm{TeV}$. \\ ( https://arxiv.org/abs/1803.10475 , 473kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10514 Date: Wed, 28 Mar 2018 10:37:57 GMT (43kb) Title: Anomalous Hall effect in dense QCD matter Authors: Toshitaka Tatsumi, Ryo Yoshiike, Kouji Kashiwa Categories: hep-ph cond-mat.mes-hall hep-th Comments: 5 pages, 2 figures Report-no: KUNS-2719, YITP-18-20 \\ In this letter, we investigate the anomalous Hall effect in dense QCD matter. When the dual chiral density wave which is the spatially modulated chiral condensate appears in the medium, it gives rise to two Weyl points to the single-particle energy-spectrum and then the anomalous Hall conductivity becomes nonzero. Then, dense QCD matter is analogous to the Weyl semimetal. The direct calculation of the Hall conductivity by way of Kubo's linear response theory gives the term proportional to the distance between the Weyl points. Unlike the Weyl semimetal, there appears the additional contribution induced by axial anomaly. \\ ( https://arxiv.org/abs/1803.10514 , 43kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10533 Date: Wed, 28 Mar 2018 11:21:04 GMT (1802kb,D) Title: Study of Isolated-photon and Jet Momentum Imbalance in $pp$ and $PbPb$ collisions Authors: Lin Chen, Guang-You Qin, Lei Wang, Shu-Yi Wei, Bo-Wen Xiao, Han-Zhong Zhang, Ya-Qi Zhang Categories: hep-ph nucl-ex nucl-th Comments: 11 pages, 6 figures \\ In this paper, we study the production of isolated-photon plus a jet in $pp$ and $PbPb$ collisions, which can be used as an important probe to the jet transport property in quark gluon plasma created in heavy ion collisions. Normally, there are two types of observables associated with the production of isolated-photon plus a jet, namely, the azimuthal angular correlation and the transverse momentum imbalance. To understand both observables in the full kinematical region, we need to employ the perturbative QCD calculation, which takes into account the hard splitting of partons, together with the Sudakov resummation formalism, which resums soft gluon splittings. Furthermore, by introducing energy-loss into the system, we calculate the enhancement of the momentum imbalance distribution for $AA$ as compared to $pp$ collisions and make predictions for future unfolded experimental data. In addition, in order to extract the jet transport coefficient more precisely in our numerical calculation, we also distinguish quark jets from gluon jets, since they interact with quark gluon plasma with different strengths. This work provides a reliable theoretical tool for the calculation of the gamma-jet correlation, which can lead us to a more precise extraction of the jet transport coefficient in relativistic heavy-ion collisions. \\ ( https://arxiv.org/abs/1803.10533 , 1802kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10546 Date: Wed, 28 Mar 2018 11:49:13 GMT (264kb) Title: A covariant interacting Hadron-Resonance Gas model Authors: Thorsten Steinert, Wolfgang Cassing Categories: hep-ph nucl-th Comments: 19 pages, 13 figures \\ The Hadron-Resonance Gas (HRG) approach - used to model hadronic matter at small baryon potentials $\mu_B $ and finite temperature $T$ - is extended to finite and large chemical potentials by introducing interactions between baryons in line with relativistic mean-field theory defining an interacting HRG (IHRG). Using lattice data for $\mu_B=0$ as well as information on the nuclear equation of state at $T=0$ we constrain the attractive and repulsive interactions of the IHRG such that it reproduces the lattice equation of state at $\mu_B=0$ and the nuclear equation of state at $T=0$ and finite $\mu_B$. The formulated covariant approach is thermodynamically consistent and allows to provide further information on the phase boundary between hadronic and partonic phases of strongly interacting matter by assuming constant thermodynamic potentials. \\ ( https://arxiv.org/abs/1803.10546 , 264kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10603 Date: Wed, 28 Mar 2018 13:39:50 GMT (13kb) Title: S-wave Heavy Quarkonium Spectra: Mass, Decays and Transitions Authors: Halil Mutuk Categories: hep-ph Comments: 10 pages, 14 Tables \\ In this paper, we studied S-wave heavy quarkonium spectra by two potential models. The first one is power potential and the second one is logarithmic potential. We calculated spin averaged masses, hyperfine splittings, decay constants, leptonic decay widhts, two-photon and two-gluon decay widths and some allowed M1 transitions. We studied ground and 4 radially excited S-wave charmonium and bottomonium states via solving nonrelativistic Schr\"{o}dinger equation via harmonic oscillator wave function. The obtained results are agree well with experimental data and other theoretical studies. \\ ( https://arxiv.org/abs/1803.10603 , 13kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10605 Date: Wed, 28 Mar 2018 13:45:32 GMT (1286kb) Title: New possibilities of hybrid texture of neutrino mass matrix Authors: Madan Singh Categories: hep-ph \\ In this paper, we investigate the noval possibilities of hybrid textures comprising a vanishing minor (or element) and two equal elements (or cofactors) in light neutrino mass matrix $M_{\nu}$. Such type of texture structures lead to sixty phenomenological cases each, out of which only fifty six are viable with texture containing a vanishing minor and an equality between the elements in $M_{\nu}$, while fifty are found to be viable with texture containing a vanishing element and an equality of cofactors in $M_{\nu}$ under the current experimental test at 3$\sigma$ confidence level. Detailed numerical analysis of all the possible cases have been presented. \\ ( https://arxiv.org/abs/1803.10605 , 1286kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10645 Date: Tue, 27 Mar 2018 12:50:27 GMT (449kb,D) Title: Slepton Production at e+e- Colliders in the Complex MSSM: A Full One-Loop Analysis Authors: S. Heinemeyer, C. Schappacher Categories: hep-ph Comments: 41 pages, 20 figures. arXiv admin note: substantial text overlap with arXiv:1704.07627, arXiv:1606.06981, arXiv:1511.06002 Report-no: IFT-UAM/CSIC-18-007 \\ For the search for scalar leptons in the Minimal Supersymmetric Standard Model (MSSM) as well as for future precision analyses of these particles an accurate knowledge of their production and decay properties is mandatory. We evaluate the cross sections for the slepton production at e+e- colliders in the MSSM with complex parameters (cMSSM). The evaluation is based on a full one-loop calculation of the production mechanisms e+e- -> slepton_s slepton_s' including soft and hard photon radiation. The dependence of the slepton production cross sections on the relevant cMSSM parameters is analyzed numerically. We find sizable contributions to many production cross sections. They amount to roughly 15% of the tree-level results but can go up to 40% or higher in extreme cases. Also the complex phase dependence of the one-loop corrections for charged slepton production was found non-negligible. The full one-loop contributions are thus crucial for physics analyses at a future linear e+e- collider such as the ILC or CLIC. \\ ( https://arxiv.org/abs/1803.10645 , 449kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10661 Date: Wed, 28 Mar 2018 14:49:48 GMT (835kb,D) Title: Updated global analysis of neutrino oscillations in the presence of eV-scale sterile neutrinos Authors: Mona Dentler, \'Alvaro Hern\'andez-Cabezudo, Joachim Kopp, Pedro A.

We work in a 3+1 framework and pay special attention to recent new data from reactor experiments, IceCube and MINOS+. We find that results from the DANSS and NEOS reactor experiments support the sterile neutrino explanation of the reactor anomaly, based on an analysis that relies solely on the relative comparison of measured reactor spectra. Global data from the $\nu_e$ disappearance channel favour sterile neutrino oscillations at the $3\sigma$ level with $\Delta m^2_{41} \approx 1.3$ eV$^2$ and $|U_{e4}| \approx 0.1$, even without any assumptions on predicted reactor fluxes. In contrast, the anomalies in the $\nu_e$ appearance channel (dominated by LSND) are in strong tension with improved bounds on $\nu_\mu$ disappearance, mostly driven by MINOS+ and IceCube. Under the sterile neutrino oscillation hypothesis, the p-value for those data sets being consistent is less than $2.6\times 10^{-6}$. Therefore, an explanation of the LSND anomaly in terms of sterile neutrino oscillations in the 3+1 scenario is excluded at the $4.7\sigma$ level. This result is robust with respect to variations in the analysis and used data, in particular it depends neither on the theoretically predicted reactor neutrino fluxes, nor on constraints from any single experiment. Irrespective of the anomalies, we provide updated constraints on the allowed mixing strengths $|U_{\alpha 4}|$ ($\alpha = e,\mu,\tau$) of active neutrinos with a fourth neutrino mass state in the eV range. \\ ( https://arxiv.org/abs/1803.10661 , 835kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10685 Date: Wed, 28 Mar 2018 15:39:11 GMT (8kb) Title: Photon in the Earth-ionosphere cavity Authors: Yusuf Sucu and Cavit Tekincay Categories: hep-ph Comments: 5 pages, 1 table \\ We study a quantum analogy of Schumann resonances by solving massless and massive spin-1 particle equations derived from the zitterbewegung model in a spherical cavity background with poor conducting walls. The poor conductivity with a quality factor helps us to derive Schumann resonances theoretically more accurately. We also show that the massless case and the massive case in the $m_0^2 \rightarrow 0$ limit are compatible with the Maxwell theory. Furthermore, from the massive case, we predict an upper limit for the mass of the photon. \\ ( https://arxiv.org/abs/1803.10685 , 8kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10735 Date: Wed, 28 Mar 2018 17:22:35 GMT (402kb) Title: The Texture One Zero Neutrino Mass Matrix With Vanishing Trace Authors: Madan Singh Categories: hep-ph \\ In the light of latest neutrino oscillation data, we have investigated the one zero Majorana neutrino mass matrix $M_{\nu}$ with zero sum condition of mass eigen values in the flavor basis, where charged lepton mass matrix is diagonal. Among the six possible one-zero cases, it is found that only five can survive the current experimental data, while case with (1, 1) vanishing element of $M_{\nu}$ is ruled out, if zero trace condition is imposed at 3$\sigma$ confidence level (CL). Numerical and some approximate analytical results are presented. \\ ( https://arxiv.org/abs/1803.10735 , 402kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10754 Date: Wed, 28 Mar 2018 17:45:10 GMT (175kb) Title: Investigating the hybrid textures of neutrino mass matrix for near maximal atmospheric neutrino mixing Authors: Madan Singh Categories: hep-ph cs.NA \\ In the present paper, we have studied that the implication of a large value of the effective Majorana neutrino mass in case of neutrino mass matrices having either two equal elements and one zero element (popularly known as hybrid texture) or two equal cofactors and one zero minor (popularly known as inverse hybrid texture) in the flavor basis. In each of these cases, four out of sixty phenomenologically possible patterns predict near maximal atmospheric neutrino mixing angle in the limit of large effective Majorana neutrino mass. This feature remains irrespective of the experimental data on solar and reactor mixing angles. In addition, we have also performed the comparative study of all the viable cases of hybrid and inverse hybrid textures at 3$\sigma$ CL. \\ ( https://arxiv.org/abs/1803.10754 , 175kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1803.10230 (*cross-listing*) Date: Tue, 27 Mar 2018 11:04:40 GMT (611kb,D) Title: A non-perturbative exploration of the high energy regime in $N_\text{f}=3$ QCD Authors: Mattia Dalla Brida, Patrick Fritzsch, Tomasz Korzec, Alberto Ramos, Stefan Sint and Rainer Sommer Categories: hep-lat hep-ph Comments: 40 pages, 11 figures Report-no: CERN-TH-2018-060, DESY 18-044, WUB/18-01 \\ Using continuum extrapolated lattice data we trace a family of running couplings in three-flavour QCD over a large range of scales from about 4 to 128 GeV. The scale is set by the finite space time volume so that recursive finite size techniques can be applied, and Schr\"odinger functional (SF) boundary conditions enable direct simulations in the chiral limit. Compared to earlier studies we have improved on both statistical and systematic errors. Using the SF coupling to implicitly define a reference scale $1/L_0\approx 4$ GeV through $\bar{g}^2(L_0) =2.012$, we quote $L_0 \Lambda^{N_{\rm f}=3}_{\overline{\rm MS}} =0.0791(21)$. This error is dominated by statistics; in particular, the remnant perturbative uncertainty is negligible and very well controlled, by connecting to infinite renormalization scale from different scales $2^n/L_0$ for $n=0,1,\ldots,5$. An intermediate step in this connection may involve any member of a one-parameter family of SF couplings. This provides an excellent opportunity for tests of perturbation theory some of which have been published in a letter [1]. The results indicate that for our target precision of 3 per cent in $L_0 \Lambda^{N_{\rm f}=3}_{\overline{\rm MS}}$, a reliable estimate of the truncation error requires non-perturbative data for a sufficiently large range of values of $\alpha_s=\bar{g}^2/(4\pi)$. In the present work we reach this precision by studying scales that vary by a factor $2^5= 32$, reaching down to $\alpha_s\approx 0.1$. We here provide the details of our analysis and an extended discussion. \\ ( https://arxiv.org/abs/1803.10230 , 611kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10256 (*cross-listing*) Date: Tue, 27 Mar 2018 18:05:43 GMT (63kb) Title: Elliptic symbol calculus: from elliptic polylogarithms to iterated integrals of Eisenstein series Authors: Johannes Broedel, Claude Duhr, Falko Dulat, Brenda Penante, Lorenzo Tancredi Categories: hep-th hep-ph math-ph math.MP Comments: 65 pages \\ We present a generalization of the symbol calculus from ordinary multiple polylogarithms to their elliptic counterparts. Our formalism is based on a special case of a coaction on large classes of periods that is applied in particular to elliptic polylogarithms and iterated integrals of modular forms. We illustrate how to use our formalism to derive relations among elliptic polylogarithms, in complete analogy with the non-elliptic case. We then analyze the symbol alphabet of elliptic polylogarithms evaluated at rational points, and we observe that it is given by Eisenstein series for a certain congruence subgroup. We apply our formalism to hypergeometric functions that can be expressed in terms of elliptic polylogarithms and show that they can equally be written in terms of iterated integrals of Eisenstein series. Finally, we present the symbol of the equal-mass sunrise integral in two space-time dimensions. The symbol alphabet involves Eisenstein series of level six and weight three, and we can easily integrate the symbol in terms of iterated integrals of Eisenstein series. \\ ( https://arxiv.org/abs/1803.10256 , 63kb) ------------------------------------------------------------------------------ \\ arXiv:1803.10571 (*cross-listing*) Date: Wed, 28 Mar 2018 13:03:44 GMT (12kb) Title: Quadratic chaotic inflation with a logarithmic-corrected mass Authors: Shinta Kasuya, Mayuko Taira Categories: astro-ph.CO hep-ph Comments: 3 pages, 1 figure \\ We consider a simple modification of the quadratic chaotic inflation.

These neutrinos were a dominant component of the energy density in the early universe and, therefore, played an important role in the evolution of cosmological perturbations. In particular, fluctuations in the neutrino density produced a distinct shift in the temporal phase of sound waves in the primordial plasma, which has recently been detected in the cosmic microwave background (CMB). In this paper, we report on the first measurement of this neutrino-induced phase shift in the spectrum of baryon acoustic oscillations (BAO) of the BOSS DR12 data. Constraining the acoustic scale using Planck data, and marginalizing over the effects of neutrinos in the CMB, we find evidence for a non-zero phase shift at greater than 95% confidence. We also demonstrate the robustness of this result in simulations and forecasts. Besides being a new measurement of the cosmic neutrino background, our work is the first application of the BAO signal to early universe physics and a non-trivial confirmation of the standard cosmological history. \\ ( https://arxiv.org/abs/1803.10741 , 2450kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1601.06637 replaced with revised version Wed, 28 Mar 2018 07:51:29 GMT (0kb,I) Title: Complete Form of Fermion Self-energy in NJL Model with External Magnetic Field Authors: Song Shi, Yi-Lun Du, Yong-Hui Xia and Hong-Shi Zong Categories: hep-ph Comments: The first author of this paper has uploaded another version of this paper with his own account, which conflicts with this version [arXiv:1802.09942] \\ ( https://arxiv.org/abs/1601.06637 , 0kb) ------------------------------------------------------------------------------ \\ arXiv:1611.00009 replaced with revised version Wed, 28 Mar 2018 06:29:43 GMT (35kb,D) Title: Radiative Yukawa Couplings in the Simplest Left-Right Symmetric Model Authors: Emidio Gabrielli, Luca Marzola and Martti Raidal Categories: hep-ph Comments: matches the version published in PRD containing an added appendix Journal-ref: Phys.
