We show that both elliptic gluon Wigner distribution and final state soft photon radiation can give rise to this azimuthal asymmetry. The fact that the QED effect alone severely underestimates the observed asymmetry might signal the existence of the nontrivial correlation in quantum phase distribution of gluons. \\ ( https://arxiv.org/abs/2106.13466 , 81kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13471 Date: Fri, 25 Jun 2021 07:35:22 GMT (1137kb,D) Title: The role of colour flows in matrix element computations and Monte Carlo simulations Authors: Stefano Frixione, Bryan R. Webber Categories: hep-ph Comments: 75 pages, 3 figures Report-no: CERN-TH-2021-098 \\ We discuss how colour flows can be used to simplify the computation of matrix elements, and in the context of parton shower Monte Carlos with accuracy beyond leading-colour. We show that, by systematically employing them, the results for tree-level matrix elements and their soft limits can be given in a closed form that does not require any colour algebra. The colour flows that we define are a natural generalization of those exploited by existing Monte Carlos; we construct their representations in terms of different but conceptually equivalent quantities, namely colour loops and dipole graphs, and examine how these objects may help to extend the accuracy of Monte Carlos through the inclusion of subleading-colour effects. We show how the results that we obtain can be used, with trivial modifications, in the context of QCD+QED simulations, since we are able to put the gluon and photon soft-radiation patterns on the same footing. We also comment on some peculiar properties of gluon-only colour flows, and their relationships with established results in the mathematics of permutations. \\ ( https://arxiv.org/abs/2106.13471 , 1137kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13534 Date: Fri, 25 Jun 2021 09:57:05 GMT (360kb,D) Title: Goldstone Boson Scattering with a Light Composite Scalar Authors: T.

To this end, we present a nonperturbative lattice calculation of s-wave scattering of Goldstone bosons in the maximal-isospin channel in SU(3) gauge theory with $N_f=8$ light, degenerate flavors. The scattering phase shift is measured both for different values of the underlying fermion mass and for different values of the scattering momentum. We examine the effect of a light flavor-singlet scalar (reported in earlier studies) on Goldstone boson scattering, employing a dilaton effective field theory (EFT) at the tree level. The EFT gives a good description of the scattering data, insofar as the magnitude of deviations between EFT and lattice data are no larger than the expected size of next-to-leading order corrections in the EFT. \\ ( https://arxiv.org/abs/2106.13534 , 360kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13592 Date: Fri, 25 Jun 2021 12:41:03 GMT (252kb,D) Title: Chiral symmetry restoration and properties of Goldstone bosons at finite temperature Authors: Yin-Zhen Xu, Si-Xue Qin, and Hong-Shi Zong Categories: hep-ph nucl-th \\ We study chiral symmetry restoration by analyzing thermal properties of QCD's (pseudo-)Goldstone boson, especially pion, by analyzing the spectral densities of mesonic imaginary-time correlation functions. To obtain the correlation functions, we solve the Dyson-Schwinger equations and the inhomogeneous Bethe-Salpeter equations in the leading symmetry-preserving rainbow-ladder approximation. In the chiral limit, the pion and its partner sigma degenerate at the critical temperature $T_c$. At $T \gtrsim T_c$, it is found that the pion rapidly dissociates, which signals deconfinement phase transition. Beyond the chiral limit, the pion dissociation temperature can be used to define the pseudo-critical temperature of chiral phase crossover, which is consistent with that obtained by the maximum point of the chiral susceptibility. The parallel analysis for kaon and pseudoscalar $s\bar{s}$ suggests that heavy mesons may survive above $T_c$. \\ ( https://arxiv.org/abs/2106.13592 , 252kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13616 Date: Fri, 25 Jun 2021 13:13:18 GMT (6546kb,D) Title: Charged and Neutral $\bar B_{u,d,s} \to \gamma$ Form Factors from Light Cone Sum Rules at NLO Authors: Tadeusz Janowski, Ben Pullin and Roman Zwicky Categories: hep-ph hep-ex Comments: 54 pp (plus refs), 13 figs, 9 tables and 4 ancillary files (z-expansion fit etc) Report-no: CP3-Origins-2020-14 DNRF90 \\ We present the first analytic ${\cal O}(\alpha_s)$-computation at twist-$1$,$2$ of the $\bar B_{u,d,s} \to \gamma$ form factors within the framework of sum rules on the light-cone. These form factors describe the charged decay $\bar B_u \to \gamma \ell^- \bar{\nu}$, contribute to the flavour changing neutral currents $\bar B_{d,s} \to \gamma \ell^+ \ell^-$ and serve as inputs to more complicated processes. We provide a fit in terms of a $z$-expansion with correlation matrix and extrapolate the form factors to the kinematic endpoint by using the $g_{BB^*\gamma}$ couplings as a constraint. Analytic results are available in terms of multiple polylogarithms as ancillary files. We give binned predictions for the $\bar B_u \to \gamma \ell^- \bar{\nu}$ branching ratio along with the associated correlation matrix. By comparing with three SCET-computations we extract the inverse moment $B$-meson distribution amplitude parameter $\lambda_B = 360 (110) \text{MeV}$. The uncertainty thereof could be improved by a more dedicated analysis. In passing, we extend the photon distribution amplitude to include quark mass corrections with a prescription for the magnetic vacuum susceptibility, $\chi_q$, compatible with the twist-expansion. The values $\chi_q = 3.21 (15) \text{GeV}^{-2}$ and $\chi_s = 3.79 (17) \text{GeV}^{-2}$ are obtained. \\ ( https://arxiv.org/abs/2106.13616 , 6546kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13617 Date: Fri, 25 Jun 2021 13:13:40 GMT (1981kb,D) Title: Radiative Decays of Heavy-light Mesons and the $f_{H,H^*,H_1}^{(T)}$ Decay Constants Authors: Ben Pullin and Roman Zwicky Categories: hep-ph hep-ex Comments: 34 pp (plus refs) and 6 figs Report-no: CP3-Origins-2020-13 DNRF90 \\ The on-shell matrix elements, or couplings $g_{H H^*(H_1)\gamma}$, describing the $B(D)_q^* \to B(D)_q \gamma$ and $B_{1 q} \to B_q \gamma$ ($q = u,d,s$) radiative decays, are determined from light-cone sum rules at next-to-leading order for the first time. Two different interpolating operators are used for the vector meson, providing additional robustness to our results. For the $D^*$-meson, where some rates are experimentally known, agreement is found. The couplings are of additional interest as they govern the lowest pole residue in the $B(D) \to \gamma$ form factors which in turn are connected to QED-corrections in leptonic decays $B(D) \to \ell \bar \nu$. Since the couplings and residues are related by the decay constants $f_{H^*(H_1)}$ and $f^T_{H^*(H_1)}$ respectively, we determine them at next-leading order as a by-product. The quantities $\{ f_{H^*}^T, f_{H_1},f_{H_1}^T\}$ have not previously been subjected to a QCD sum rule determination. All results are compared with the existing experimental and theoretical literature. \\ ( https://arxiv.org/abs/2106.13617 , 1981kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13628 Date: Fri, 25 Jun 2021 13:32:02 GMT (491kb,D) Title: Reformulation of a likelihood approach to fake-lepton estimation in the framework of Bayesian inference Authors: Johannes Erdmann, Cornelius Grunwald, Kevin Kr\"oninger, Salvatore La Cagnina, Lars R\"ohrig, Erich Varnes Categories: hep-ph hep-ex \\ Prompt isolated leptons are essential in many analyses in high-energy particle physics but are subject to fake-lepton background, i.e. objects that mimic the lepton signature. The fake-lepton background is difficult to estimate from simulation and is often directly determined from data. A popular method is the matrix method, which however suffers from several limitations. This paper recapitulates an alternative approach based on a likelihood with Poisson constraints and reformulates the problem from a different starting point in the framework of Bayesian statistics. The equality of both approaches is shown and several cases are studied in which the matrix method is limited. In addition, the fake lepton background is recalculated and compared to the estimate with the matrix method in an example top-quark measurement. \\ ( https://arxiv.org/abs/2106.13628 , 491kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13656 Date: Fri, 25 Jun 2021 14:21:33 GMT (929kb,D) Title: New Discovery Modes for a Light Charged Higgs Boson at the LHC Authors: A. Arhrib, R. Benbrik, M. Krab, B. Manaut, S. Moretti, Yan Wang and Qi-Shu Yan Categories: hep-ph Comments: 17 pages, 5 figures \\ At the Large Hadron Collider (LHC), both the ATLAS and CMS Collaborations have been searching for light charged Higgs bosons via top (anti)quark production and decays channels, like $pp\to t \bar{t}$ with one top (anti)quark decaying into a charged Higgs boson and a $b$ (anti)quark, when the decay is kinematically open (i.e., when $m_{H^\pm}\lesssim m_t$). In this paper, we propose new searches at the LHC involving light charged Higgs bosons via their pair production channels like $pp\to H^\pm h/A$ and $pp\to H^+ H^-$ in the 2-Higgs Doublet Model (2HDM) Type-I and -X scenarios. By focusing on the case where the heavy $H$ state plays the role of the Standard Model (SM)-like Higgs boson with a mass near 125 GeV, we study the aforementioned Higgs boson pair production channels and investigate their bosonic decays, such as $H^\pm \to W^{\pm } h$ and/or $H^\pm \to W^{\pm } A$. We demonstrate that for a light charged Higgs boson state, with $m_{H^\pm}\lesssim m_t$, at the LHC, such di-Higgs production and decay channels can give rise to signatures with event rates much larger than those emerging from $pp\to t\bar{t}\to t\bar{b} H^-$ + c.c. We specifically study $h/A\to b\bar b$ and $\tau^+\tau^-$ decays. We, therefore, claim that the discussed combination of new production and decay modes can result in an alternative discovery channel for charged Higgs bosons lighter than the top (anti)quark at the LHC within the above two 2HDM Types. Finally, in order to motivate experimentalists in ATLAS and CMS to search for such signatures, we propose 16 Benchmark Points (BPs) which are compatible with both theoretical and experimental constraints. \\ ( https://arxiv.org/abs/2106.13656 , 929kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13661 Date: Fri, 25 Jun 2021 14:26:57 GMT (1478kb,D) Title: Towards EPPS21 nuclear PDFs Authors: Kari J.

Di Piazza and T. P\u{a}tuleanu Categories: hep-ph Comments: 21 pages, 3 figures \\ Upcoming experiments on the interaction of electrons with intense laser fields are envisaged to become more and more accurate, which calls for theoretical computations of rates and probabilities with correspondingly higher precision. In strong-field QED this requires the knowledge of radiative corrections to be added to leading-order results. Here, we first derive the mass operator in momentum space of an off-shell electron in the presence of an arbitrary plane wave. By taking the average of the mass operator in momentum space over an on-shell electron state, we obtain a new representation, equivalent to but more compact than the known one computed in [Sov. Phys. JETP \textbf{42}, 400 (1975)]. Moreover, we use the obtained mass operator to determine the electron mass shift in an arbitrary plane wave, which generalizes the already known expression in a constant crossed field. The spin-dependent part of the electron mass shift can be related to the anomalous magnetic moment of the electron in the plane wave. We show that within the locally constant field approximation it is possible to conveniently define a local expression of the electron anomalous magnetic moment, which reduces to the known expression in a constant crossed field. Beyond the locally constant field approximation, however, the interaction between the electron and the plane wave is non-local such that it is not possible to conveniently introduce an electron anomalous magnetic moment. \\ ( https://arxiv.org/abs/2106.13720 , 28kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13775 Date: Fri, 25 Jun 2021 17:22:30 GMT (77kb,D) Title: Correcting event-by-event fluctuations in heavy-ion collisions for exact global conservation laws with the generalized subensemble acceptance method Authors: Volodymyr Vovchenko Categories: hep-ph nucl-th Comments: 13 pages, 2 figures \\ We introduce the subensemble acceptance method 2.0 (SAM-2.0) -- a procedure to correct cumulants of a random number distribution inside a subsystem for the effect of exact global conservation of a conserved quantity to which this number is correlated, with applications to measurements of event-by-event fluctuations in heavy-ion collisions. The method expresses the corrected cumulants in terms of the cumulants inside and outside the subsystem that are not subject to the exact conservation. The derivation assumes that all probability distributions associated with the cumulants are peaked at the mean values but are otherwise of arbitrary shape. The formalism reduces to the original SAM [V. Vovchenko et al., Phys.Lett.B 811 (2020) 135868 [arXiv:2003.13905]] when applied to a coordinate space subvolume of a uniform thermal system. As the new method is restricted neither to the uniform systems nor to the coordinate space, it is applicable to fluctuations measured in heavy-ion collisions at various collision energies in different momentum space acceptances. The SAM-2.0 thus brings the experimental measurements and theoretical calculations of event-by-event fluctuations closer together, as the latter are typically performed without the account of exact global conservation. \\ ( https://arxiv.org/abs/2106.13775 , 77kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13794 Date: Fri, 25 Jun 2021 17:45:59 GMT (15kb) Title: A methodology for theory uncertainties in the SMEFT Authors: Michael Trott Categories: hep-ph hep-ex Comments: 7 pages \\ A process specific methodology is defined to systematically assign theoretical uncertainties in the Standard Model Effective Field Theory when performing leading order global fits.

Shapiro, Taha Dawoodbhoy, Tanja Rindler-Daller Categories: astro-ph.CO astro-ph.GA hep-ph Comments: 29 pages, 10 figures, submitted to MNRAS, comments welcome \\ Scalar Field Dark Matter (SFDM) comprised of ultralight ($\gtrsim 10^{-22}$ eV) bosons is an alternative to standard, collisionless Cold Dark Matter (CDM) that is CDM-like on large scales but inhibits small-scale structure formation. As a Bose-Einstein condensate, its free-field ("fuzzy") limit (FDM) suppresses structure below the de Broglie wavelength, $\lambda_\text{deB}$, creating virialized haloes with central cores of radius $\sim\lambda_\text{deB}$, surrounded by CDM-like envelopes, and a halo mass function (HMF) with a sharp cut-off on small scales. With a strong enough repulsive self-interaction (SI), structure is inhibited, instead, below the Thomas-Fermi (TF) radius, $R_\text{TF}$ (the size of an SI-pressure-supported ($n=1$)-polytrope), when $R_\text{TF} > \lambda_\text{deB}$. Previously, we developed tools to describe SFDM dynamics on scales above $\lambda_\text{deB}$ and showed that SFDM-TF haloes formed by Jeans-unstable collapse from non-cosmological initial conditions have $R_\text{TF}$-sized cores, surrounded by CDM-like envelopes. Revisiting SFDM-TF in the cosmological context, we simulate halo formation by cosmological infall and collapse, and derive its transfer function from linear perturbation theory to produce cosmological initial conditions and predict statistical measures of structure formation, such as the HMF. Since FDM and SFDM-TF transfer functions both have small-scale cut-offs, we can align them to let observational constraints on FDM proxy for SFDM-TF, finding FDM with particle masses $1 \lesssim m/(10^{-22} \text{ eV}/c^2) \lesssim 30$ corresponds to SFDM-TF with $10 \gtrsim R_\text{TF}/(1 \text{ pc}) \gtrsim 1$, favoring sub-galactic (sub-kpc) core-size. The SFDM-TF HMF cuts off gradually, however, leaving more small-mass haloes: its Jeans mass shrinks so fast, scales filtered early can still recover and grow! \\ ( https://arxiv.org/abs/2106.13244 , 2481kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13284 (*cross-listing*) Date: Thu, 24 Jun 2021 19:17:49 GMT (4400kb,D) Title: The Milky Way, Coming into Focus: Precision Astrometry Probes its Evolution, and its Dark Matter Authors: Susan Gardner, Samuel D.

We summarize the current status of our understanding of the structure and the characteristics of the Milky Way, and we review the emerging picture: the Milky Way is evolving through interactions with the massive satellite galaxies that stud its volume, with evidence pointing to a cataclysmic past. It is also woven with stellar streams, and observations of streams, satellites, and field stars offer new constraints on its dark matter, both on its spatial distribution and its fundamental nature. The recent years have brought much focus to the study of dwarf galaxies found within our Galaxy's halo and their internal matter distributions. In this review, we focus on the predictions of the cold dark matter paradigm at small mass scales through precision astrometric measurements, and we summarize the modern consensus on the extent to which small-scale probes are consistent with this paradigm. We note the discovery prospects of these studies, and also how they intertwine with probes of the dynamics and evolution of the Milky Way in various and distinct ways. \\ ( https://arxiv.org/abs/2106.13284 , 4400kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13335 (*cross-listing*) Date: Thu, 24 Jun 2021 21:47:00 GMT (33kb) Title: A False Vacuum Skyrme Model for Nuclear Matter Authors: L. A. Ferreira and L. R. Livramento Categories: hep-th hep-lat hep-ph nucl-th Comments: 13 pages, 2 figures \\ The low energy regime of Quantum Chromodynamics (QCD) presents enormous challenges due to is large coupling. Effective field theories, like the Skyrme model, are useful approaches to study properties of strong interaction at hadronic scales. We propose a Skyrme-type model with a self-dual sector and that treats the density of the baryonic charge as a self-interacting fluid. The dynamics reduces to Coleman's false vacuum problem for a scalar field that is a fractional power of that density. The main result is that such a Skyrme-type model is the first one to reproduce, with good accuracy, the experimental values of radii and binding energies for a very wide range of the mass number. The robust and simple properties of the model lead to many possible generalisations with implications not only in nuclear physics but also in other areas of Physics. \\ ( https://arxiv.org/abs/2106.13335 , 33kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13450 (*cross-listing*) Date: Fri, 25 Jun 2021 06:27:44 GMT (948kb) Title: Tidal Deformation and Radial Pulsations of Neutron Star with Holographic Multiquark Core Authors: Sitthichai Pinkanjanarod, Piyabut Burikham, Supakchai Ponglertsakul Categories: gr-qc hep-ph Comments: 8 pages, 4 figures \\ Tidal deformation of neutron star with multiquark core is calculated using nuclear and multiquark equations of state. The equation of state of the multiquark phase from the holographic Sakai-Sugimoto~(SS) model is relatively stiff in the low density region and becomes softer at high densities. The values of Love number and dimensionless deformation parameter, $k_{2}$ and $\Lambda$, are found to be within the physically viable range under the present constraints. Radial pulsation frequencies of the multiquark core for $n=0-5$ modes are calculated for the entire mass range. For $M_{\rm core}\simeq 2 M_{\odot}$, the fundamental-mode frequency is approximately $5-6$ kHz for the energy density scale $\epsilon_{s}=23.2037$ GeV/fm$^{3}$ of the holographic SS model, this frequency is proportional to $\sqrt{\epsilon_{s}}$. \\ ( https://arxiv.org/abs/2106.13450 , 948kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13484 (*cross-listing*) Date: Fri, 25 Jun 2021 07:56:46 GMT (681kb,D) Title: Gravitational Collider Physics via Pulsar-Black Hole Binaries II: Fine and Hyperfine Structures are Favored Authors: Xi Tong, Yi Wang and Hui-Yu Zhu Categories: astro-ph.HE gr-qc hep-ph hep-th Comments: 9 pages, 4 figures \\ A rotating black hole can be clouded by light bosons via superradiance, and thus acquire an atom-like structure. If such a gravitational atom system is companioned with a pulsar, the pulsar can trigger transitions between energy levels of the gravitational atom, and these transitions can be detected by pulsar timing. We show that in such pulsar-black hole systems, fine and hyperfine structure transitions are more likely to be probed than the Bohr transition. Also, the calculation of these fine and hyperfine structure transitions are under better analytic control. Thus, these fine and hyperfine structure transitions are more ideal probes in the search for gravitational collider signals in pulsar-black hole systems. \\ ( https://arxiv.org/abs/2106.13484 , 681kb) ------------------------------------------------------------------------------ \\ arXiv:2106.13769 (*cross-listing*) Date: Fri, 25 Jun 2021 17:10:34 GMT (1314kb,D) Title: The Minimum Testable Abundance of Primordial Black Holes at Future Gravitational-Wave Detectors Authors: V.
