Title: How the axial anomaly controls flavor mixing among mesonsComments: 7 pages, 1 TableSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Lattice (heplat)
It is well known that because of the axial anomaly in QCD, mesons with $J^P = 0^$ are close to $SU(3)_{\mathrm{V}}$ eigenstates: the $\eta^\prime$ meson is largely a singlet, and the $\eta$ meson an octet. In contrast, states with $J^P = 1^$ are flavor diagonal: e.g., the $\phi$ is almost pure $\bar{s} s$. Using effective Lagrangians, we show how this generalizes to states up to spin two, assuming that they can be classified according to the unbroken chiral symmetry of $G_{\mathrm{fl}} = SU(3)_{\mathrm{L}} \times SU(3)_{\mathrm{R}}$. We construct effective Lagrangians from terms invariant under $G_{\mathrm{fl}}$, and introduce the concept of hetero and homo chiral multiplets. Because of the axial anomaly, only terms invariant under the $Z(3)_{\mathrm{A}}$ subgroup of the axial $U(1)_{\mathrm{A}}$ enter. For heterochiral multiplets, which begin with that including the $\eta$ and $\eta^\prime$, there are $Z(3)_{\mathrm{A}}$ invariant terms with low mass dimension which cause states to mix according to $SU(3)_{\mathrm{V}}$ flavor. For homochiral multiplets, which begin with that including the $\phi$, there are no $Z(3)_{\mathrm{A}}$ invariant terms with low mass dimension, and so states are diagonal in flavor. In this way we predict the flavor mixing for the heterochiral multiplet with spin one, as well as for hetero and homochiral multiplets with spin two.

Title: On the observable spectrum of theories with a BroutEnglertHiggs effectComments: 19 pages, 9 TablesSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Lattice (heplat); High Energy Physics  Theory (hepth)
The physical, observable spectrum in gauge theories is made up from gaugeinvariant states. In the standard model the Fr\"ohlichMorchioStrocchi mechanism shows that these states can be adequately mapped to the gaugedependent elementary $W$, $Z$ and Higgs states. In theories with a more general gauge group and Higgs sector this is no longer necessarily the case. We classify and predict the physical spectrum for a wide range of such theories, with special emphasis on GUTlike cases, and show that discrepancies between the spectrum of elementary fields and physical particles frequently arise.

Title: Solving differential equations for Feynman integrals by expansions near singular pointsSubjects: High Energy Physics  Phenomenology (hepph)
We describe a strategy to solve differential equations for Feynman integrals by powers series expansions near singular points and to obtain high precision results for the corresponding master integrals. We consider Feynman integrals with two scales, i.e. nontrivially depending on one variable. The corresponding algorithm is oriented at situations where canonical form of the differential equations is impossible. We provide a computer implementation of our algorithm in a simple example of fourloop generalized sunset integrals with three equal nonzero masses. Our code provides values of the master integrals at any given point on the real axis with a required accuracy and a given order of expansion in the regularization parameter $\epsilon$.

Title: Massless onshell box integral with arbitrary powers of propagatorsAuthors: O. V. TarasovComments: 9 pages, 1figureSubjects: High Energy Physics  Phenomenology (hepph)
The massless oneloop box integral with arbitrary indices in arbitrary spacetime dimension $d$ is shown to reduce to a sum over three generalised hypergeometric functions. This result follows from the solution to the third order differential equation of hypergeometric type. To derive the differential equation, the Gr\"obner basis technique for integrals with noninteger powers of propagators was used. A complete set of recurrence relations from the Gr\"obner basis is presented. The first several terms in the $\varepsilon =(4d)/2$ expansion of the result are given.

Title: Gravitational Waves from Hidden QCD Phase TransitionComments: 30 pages, 16 figuresSubjects: High Energy Physics  Phenomenology (hepph)
Drastic changes in the early universe such as firstorder phase transition can produce a stochastic gravitational wave (GW) background. We investigate the testability of a scale invariant extension of the standard model (SM) using the GW background produced by the chiral phase transition in a strongly interacting QCDlike hidden sector, which, via a SM singlet real scalar mediator, triggers the electroweak phase transition. Using the NambuJonaLasinio method in a mean field approximation we estimate the GW signal and find that it can be tested by future space based detectors.

Title: Possible roles of PecceiQuinn symmetry in an effective low energy modelAuthors: Daijiro SuematsuComments: 14 pages, 2 figuresSubjects: High Energy Physics  Phenomenology (hepph)
Strong $CP$ problem is known to be solved by imposing PecceiQuinn (PQ) symmetry. However, domain wall problem caused by the spontaneous breaking of its remnant discrete subgroup could make models invalid in many cases. We propose a model in which the PQ charge is assigned quarks so as to escape this problem without introducing any extra colored fermions. In the low energy effective model resulting after the PQ symmetry breaking, both the quark mass hierarchy and the CKM mixing could be explained through FroggattNielsen mechanism. If the model is combined with the lepton sector supplemented by an inert doublet scalar and righthanded neutrinos, the effective model reduces to the scotogenic neutrino mass model in which both the origin of neutrino masses and dark matter are closely related. The strong $CP$ problem could be related to the quark mass hierarchy, neutrino masses and dark matter through the PQ symmetry.

Title: Spontaneous mass generation suggests small dimension of the SM group U(1)xSU(2)xSU(3)Comments: Contribution to the EPS conference on High Energy Physics, Venice, Italy, 5th12th July 2017. 3+1 pages, 2 figuresSubjects: High Energy Physics  Phenomenology (hepph)
The reasons behind the gauge symmetry of the Standard Model, U(1)xSU(2)xSU(3), are still unsettled. One obvious feature is the low dimensionality of all its subgroups. Under certain conditions, a negative answer to the question "why not larger groups like SU(15), or for that matter, SP(26) or E7?" is possible.
We have recently observed that fermions charged under large groups acquire much bigger dynamical masses, all things being equal at a high e.g. GUT scale, than ordinary quarks. Should such multicharged fermions exist, they are just too heavy to be observed today (and have either decayed early on if coupled to the rest of the Standard Model, or become reliquial dark matter if uncoupled). Their mass scale is dictated by strong antiscreening of the running coupling for those larger groups (with an appropriately small number of flavors) together with scaling properties of the DysonSchwinger equation for the fermion mass.
The generated fermion mass (assuming only few flavors, to avoid spoiling antiscreening) grows exponentially with the number of colors as M(N_c) ~ exp(N_c) for scales much below the GUT scale. Large groups would be strongly coupled already near the GUT scale and fermions charged thereunder have correspondingly large masses.  [8] arXiv:1709.07670 [pdf, other]

Title: Phenomenology of MajoronsAuthors: Julian HeeckComments: 4 pages. Contributed to the 13th Patras Workshop on Axions, WIMPs and WISPs, Thessaloniki, May 15 to 19, 2017Subjects: High Energy Physics  Phenomenology (hepph)
Majorons are the Goldstone bosons associated to lepton number and thus closely connected to Majorana neutrino masses. Couplings to charged fermions arise at oneloop level, including leptonflavorviolating ones that lead to decays $\ell\to \ell' J$, whereas a coupling to photons is generated at two loops. The typically small couplings make massive majorons a prime candidate for longlived dark matter. Its signature decay into two monoenergetic neutrinos is potentially detectable for majoron masses above MeV.

Title: Calculation of the Decay Rate of Tachyonic Neutrinos against ChargedLeptonPair and NeutrinoPair Cerenkov RadiationComments: 29 pages; RevTeXJournalref: J.Phys.G 44 (2017) 105201Subjects: High Energy Physics  Phenomenology (hepph)
We consider in detail the calculation of the decay rate of highenergy superluminal neutrinos against (charged) lepton pair Cerenkov radiation (LPCR), and neutrino pair Cerenkov radiation (NPCR), i.e., against the decay channels nu > nu e+ e and nu > nu nubar nu. Under the hypothesis of a tachyonic nature of neutrinos, these decay channels put constraints on the lifetime of highenergy neutrinos for terrestrial experiments as well as on cosmic scales. For the oncoming neutrino, we use the Lorentzcovariant tachyonic relation E_nu = (p^2  m_nu^2)^(1/2), where m_nu is the tachyonic mass parameter. We derive both threshold conditions as well as decay and energy loss rates, using the planewave fundamental bispinor solutions of the tachyonic Dirac equation. Various intricacies of rest frame versus lab frame calculations are highlighted. The results are compared to the observations of highenergy IceCube neutrinos of cosmological origin.

Title: The fiveloop Beta function for a general gauge group and anomalous dimensions beyond Feynman gaugeComments: 17 pages, 2 ancillary files files available with the sourceSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
We focus on a nonabelian gauge field coupled to a single (but general) representation of a family of Nf fermions. By using the same machinery that had allowed us to evaluate the subleading largeNf term of the fiveloop Beta function earlier, we here report on a confirmation of the allNf result that has in the meantime been published by another group. Furthermore, in order to push forward the 5loop renormalization program regarding gauge parameter dependence, we present the linear terms of the complete set of anomalous dimensions, in an expansion in the covariant gauge parameter around the Feynman gauge.

Title: Some Phenomenologies of a Simple Scotogenic Inverse Seesaw ModelAuthors: YiLei TangSubjects: High Energy Physics  Phenomenology (hepph)
In this paper, we discuss and calculate the electroweak parameters $R_l$, $A_l$, and $N_{\nu}^l$ in a model that combine inverse seesaw with the scotogenic model. Dark matter relic density is also considered. Due to the stringent constraint from the ATLAS experimental data, it is difficult to detect the loop effect on $R_l$, $A_l$ in this model considering both the theoretical and future experimental uncertainties. However, $N_{\nu}^l$ can sometimes become large enough for the future experiments to verify.

Title: Photonjet correlations at RHIC and the LHCAuthors: M. KlasenComments: 4 pages, 3 figuresSubjects: High Energy Physics  Phenomenology (hepph)
We present POWHEG predictions for photonjet correlations at RHIC and the LHC. We show that the total transversemomentum spectrum of photons and jets is modified not only by medium, but also by higherorder QCD effects, as is the distribution in their relative azimuthal angle. At the LHC, photonjet measurements in the forward region allow to probe parton momentum fractions of lead ions down to 10$^{4}$.

Title: TwoLoop Renormalization Group Equations and Gauge Couplings UnificationAuthors: Antonio CostantiniComments: 20 pages, 23 figures, 1 tableSubjects: High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
We analize the impact of twoloop renormalization group equations on the $SU(3)_c\times SU(2)_w\times U(1)_Y$ gauge couplings unification in various supersymmetric theories. In general the presence of superfields in higher representation than the doublet spoil the gauge couplings unification at oneloop. The situation is more interesting when the renormalization group equations are calculated at twoloop. In this case we show that the unification of the gauge couplings can be achieved for models with triplet superfield(s). In the analysis of the models with triplet superfield(s) we show that the dimensionless couplings do not have a Landau pole in their evolution at high energies but they run to a nontrivial ultraviolet fixed point.

Title: Effects of the temperature and magneticfield dependent coupling on the properties of QCD matterComments: 7 pages, 7 figures, version accepted for publication in Phys. Rev. DSubjects: High Energy Physics  Phenomenology (hepph)
To reflect the asymptotic freedom in the thermal direction, a temperaturedependent coupling was proposed in the literature. We investigate its effect on QCD matter with and without strong magnetic fields. Compared with the fixed coupling constant, the running coupling leads to a drastic change in the dynamical quark mass, entropy density, sound velocity, and specific heat. The crossover transition of QCD matter at finite temperature is characterized by the pseudocritical temperature $T_\mathrm{pc}$, which is generally determined by the peak of the derivative of the quark condensate with respect to the temperature $d\phi/dT$, or equivalently, by the derivative of the quark dynamical mass $d M/dT$. In a strong magnetic field, the temperature and magneticfielddependent coupling $G(eB,T)$ was recently introduced to account for inverse magnetic catalysis. We propose an analytical relation between the two criteria $d\phi/dT$ and $dM/dT$ and show a discrepancy between them in finding the pseudocritical temperature. The magnitude of the discrepancy depends on the behavior of $dG/dT$.

Title: Reconstruction of topquark mass effects in Higgs pair production and other gluonfusion processesComments: 37 pages, 10 figuresSubjects: High Energy Physics  Phenomenology (hepph)
We propose a novel method for the treatment of topquark mass effects in the production of $H^{(*)}$, $HH$, $HZ$ and $ZZ$ final states in gluon fusion. We show that it is possible to reconstruct the full topquark mass dependence of the virtual amplitudes from the corresponding large$m_t$ expansion and the nonanalytic part of the amplitude near the topquark threshold $\hat{s}=4m_t^2$ with a Pad\'e ansatz. The reliability of our method is clearly demonstrated by a comparison with the recent NLO result for Higgs pair production with full topquark mass dependence.

Title: QED and QCD selfenergy corrections through the looptree dualityComments: 9 pages, 1 figure, To be published in Journal of Physics Conference Series (IOP). Joint Proceedings of the XXXI Annual Meeting of the Division of Particles and Fields of the Mexican Physical SocietySubjects: High Energy Physics  Phenomenology (hepph)
The looptree duality (LTD) theorem establishes that loop contributions to scattering amplitudes can be computed through dual integrals, which are build from single cuts of the virtual diagrams. In order to build a complete LTD representation of a cross section and to achieve a local cancellation of singularities, it is crucial to include the renormalized selfenergy corrections in an unintegrated form. In this document, we calculate the scalar functions related to the selfenergy corrections in QED and QCD in the LTD formalism and extract explicitly their UV behaviour.

Title: Positivity bounds on gluon TMDs for hadrons of spin $\le$ 1Comments: 10 pagesSubjects: High Energy Physics  Phenomenology (hepph)
We consider the transverse momentum dependent gluon distribution functions (called gluon TMDs) by studying the lightfront gluongluon correlator, extending the results for unpolarized and vector polarized targets to also include tensor polarized targets  the latter type of polarization is relevant for targets of spin $\ge1$. The lightfront correlator includes processdependent gauge links to guarantee color gauge invariance. As from the experimental side the gluon TMDs are largely unknown, we present positivity bounds for combinations of leadingtwist gluon distributions that may be used to estimate their maximal contribution to observables. Since the gluonic content of hadrons is particularly relevant in the small$x$ kinematic region, we also study these bounds in the small$x$ limit for the dipoletype gauge link structure using matrix elements of a single Wilson loop.

Title: Freezeout of baryon number in lowscale leptogenesisComments: 17 pages, 6 figuresSubjects: High Energy Physics  Phenomenology (hepph); Cosmology and Nongalactic Astrophysics (astroph.CO)
Lowscale leptogenesis provides an economic and testable description of the origin of the baryon asymmetry of the Universe. In this scenario, the baryon asymmetry of the Universe is reprocessed from the lepton asymmetry by electroweak sphaleron processes. Provided that sphalerons are fast enough to maintain equilibrium, the values of the baryon and lepton asymmetries are related to each other. Usually, this relation is used to find the value of the baryon asymmetry at the time of the sphaleron freezeout. To put in other words, the formula which is valid only when the sphalerons are fast, is applied at the moment when they are actually switched off. In this paper, we examine the validity of such a treatment. To this end, we solve the full system of kinetic equations for lowscale leptogenesis. This system includes equations describing the production of the lepton asymmetry in oscillations of righthanded neutrinos, as well as a separate kinetic equation for the baryon asymmetry. We show that for some values of the model parameters, the corrections to the standard approach are sizeable. We also present a feasible improvement to the ordinary procedure, which accounts for these corrections.

Title: Spin Precession Experiments for Light Axionic Dark MatterAuthors: Peter W. Graham, David E. Kaplan, Jeremy Mardon, Surjeet Rajendran, William A. Terrano, Lutz Trahms, Thomas WilkasonComments: 18 pages, 4 figuresSubjects: High Energy Physics  Phenomenology (hepph); Cosmology and Nongalactic Astrophysics (astroph.CO); High Energy Physics  Experiment (hepex); Atomic Physics (physics.atomph)
Axionlike particles are promising candidates to make up the dark matter of the universe, but it is challenging to design experiments that can detect them over their entire allowed mass range. Dark matter in general, and in particular axionlike particles and hidden photons, can be as light as roughly $10^{22} \;\rm{eV}$ ($\sim 10^{8} \;\rm{Hz}$), with astrophysical anomalies providing motivation for the lightest masses ("fuzzy dark matter"). We propose experimental techniques for direct detection of axionlike dark matter in the mass range from roughly $10^{13} \;\rm{eV}$ ($\sim 10^2 \;\rm{Hz}$) down to the lowest possible masses. In this range, these axionlike particles act as a timeoscillating magnetic field coupling only to spin, inducing effects such as a timeoscillating torque and periodic variations in the spinprecession frequency with the frequency and direction set by fundamental physics. We show how these signals can be measured using existing experimental technology, including torsion pendulums, atomic magnetometers, and atom interferometry. These experiments demonstrate a strong discovery capability, with future iterations of these experiments capable of pushing several orders of magnitude past current astrophysical bounds.

Title: Status of the asymptotic safety paradigm for quantum gravity and matterAuthors: Astrid EichhornComments: 21 pages; extended version of a talk given at the workshop on Black Holes, Gravitational Waves and Spacetime Singularities, May 2017, Specola Vaticana; prepared for the proceedings of the workshopSubjects: General Relativity and Quantum Cosmology (grqc); High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
In the asymptotic safety paradigm, a quantum field theory reaches a regime with quantum scale invariance in the ultraviolet, which is described by an interacting fixed point of the Renormalization Group. Compelling hints for the viability of asymptotic safety in quantum gravity exist, mainly obtained from applications of the functional Renormalization Group. The impact of asymptotically safe quantum fluctuations of gravity at and beyond the Planck scale could at the same time induce an ultraviolet completion for the Standard Model of particle physics with high predictive power.

Title: Analysis of Ultra High Energy Muons at the INOICAL Using PairMeter TechniqueComments: Presented in Advanced Detectors for Nuclear, High Energy and Astroparticle Physics  Bose Institute Kolkata, IndiaSubjects: Instrumentation and Detectors (physics.insdet); High Energy Physics  Phenomenology (hepph)
The proposed ICAL detector at INO is a large sized underground magnetized iron detector. ICAL is designed to reconstruct muon momentum using magnetic spectrometers. Energy measurement using magnets fail for muons in TeV range, since the angular deflection of the muon in the magnetic field is negligible and the muon tracks become nearly straight. A new technique for measuring the energy of muons in the TeV range is used by the CCFR neutrino detector, known as the PairMeter technique. This technique estimates muon energy from measurements of the energy deposited by the muon in many layers of an ironcalorimeter through e$^+$ and e$^$ pair production. In this work we have performed Geant4 based preliminary analysis for iron plates and have demonstrated the observational feasibility of very high energy muons (1TeV1000TeV) in a large mass underground detector operating as a pairmeter. This wide range of energy spectrum will be helpful for studying the cosmic rays in the Knee region and an understanding of the atmospheric neutrino flux for the present and future ultra highenergy atmospheric neutrino experiments.

Title: Vacuum dynamics in the Universe versus a rigid $Λ=$constComments: Published in Int. J. Mod. Phys. A32 (2017) 1730014. arXiv admin note: text overlap with arXiv:1705.06723Subjects: Cosmology and Nongalactic Astrophysics (astroph.CO); General Relativity and Quantum Cosmology (grqc); High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
In this year, in which we celebrate 100 years of the cosmological term, $\Lambda$, in Einstein's gravitational field equations, we are still facing the crucial question whether $\Lambda$ is truly a fundamental constant or a mildly evolving dynamical variable. After many theoretical attempts to understand the meaning of $\Lambda$, and in view of the enhanced accuracy of the cosmological observations, it seems now mandatory that this issue should be first settled empirically before further theoretical speculations on its ultimate nature. In this work, we summarize the situation of some of these studies. Devoted analyses made recently show that the $\Lambda=$const. hypothesis, despite being the simplest, may well not be the most favored one. The overall fit to the cosmological observables $SNIa+BAO+H(z)+LSS+CMB$ singles out the class RVM of the "running" vacuum models, in which $\Lambda=\Lambda(H)$ is an affine powerlaw function of the Hubble rate. It turns out that the performance of the RVM as compared to the "concordance" $\Lambda$CDM model (with $\Lambda=$const.) is much better. The evidence in support of the RVM may reach $\sim 4\sigma$ c.l., and is bolstered with Akaike and Bayesian criteria providing strong evidence in favor of the RVM option. We also address the implications of this framework on the tension between the CMB and local measurements of the current Hubble parameter.

Title: Primordial nonGaussianity and power asymmetry with quantum gravitational effects in loop quantum cosmologyComments: revtex4, one figure and no tablesSubjects: Cosmology and Nongalactic Astrophysics (astroph.CO); General Relativity and Quantum Cosmology (grqc); High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
Loop quantum cosmology (LQC) provides a resolution of the classical big bang singularity in the deep Planck era. The evolution, prior to the usual slowroll inflation, naturally generates excited states at the onset of the slowroll inflation. It is expected that these quantum gravitational effects could leave its fingerprints on the primordial perturbation spectrum and nonGaussianity, and lead to some observational evidences in the cosmic microwave background (CMB). While the impact of the quantum effects on the primordial perturbation spectrum has been already studied and constrained by current data, in this paper we continue studying such effects on the nonGaussianity of the primordial curvature perturbations. In this paper, we present detailed and analytical calculations of the nonGaussianity and show explicitly that the corrections due to quantum effects are in the same magnitude of the slowroll parameters in the observable scales and thus are well within current observational constraints. Despite this, we show that the nonGaussianity in the squeezed limit can be enhanced at superhorizon scales and further, these effects may yield a large statistical anisotropy on the power spectrum through the ErickcekKamionkowskiCarroll mechanism.

Title: Can the graviton have a large mass near black holes?Comments: 6 pages, 4 figuresSubjects: General Relativity and Quantum Cosmology (grqc); High Energy Astrophysical Phenomena (astroph.HE); High Energy Physics  Phenomenology (hepph); High Energy Physics  Theory (hepth)
The mass of the graviton, if nonzero, is usually considered to be very small, e.g. of the Hubble scale, from several observational constraints. In this paper, we propose a gravity model where the graviton mass is very small in the usual weak gravity environments, below all the current graviton mass bounds, but becomes much larger in the strong gravity regime such as a black hole's vicinity. For black holes in this model, significant deviations from general relativity emerge very close to the black hole horizon and alter the black hole quasinormal modes, which can be extracted from the ringdown waveform of black hole binary mergers. Also, the enhancement of the graviton mass near the horizon can result in echoes in the late time ringdown, which can be verified in the upcoming gravitational wave observations of higher sensitivity.

We discuss the current developments by the European Twisted Mass Collaboration in extracting parton distribution functions from the quasiPDF approach. We concentrate on the nonperturbative renormalization prescription recently developed by us, using the RI$'$ scheme. We show results for the renormalization functions of matrix elements needed for the computation of quasiPDFs, including the conversion to the $\overline{\rm MS}$ scheme, and for renormalized matrix elements. We discuss the systematic effects present in the $Z$factors and the possible ways of addressing them in the future.

Title: Thermal quarkonium physics in the pseudoscalar channelComments: 28 pagesSubjects: High Energy Physics  Lattice (heplat); High Energy Physics  Phenomenology (hepph)
The pseudoscalar correlator is an ideal lattice probe for thermal modifications to quarkonium spectra, given that it is not compromised by a contribution from a large transport peak. We construct a perturbative spectral function incorporating resummed thermal effects around the threshold and vacuum asymptotics above the threshold, and compare the corresponding imaginarytime correlators with continuumextrapolated lattice data for quenched SU(3) at several temperatures. Modest differences are observed, which may originate from nonperturbative mass shifts or renormalization factors, however no resonance peaks are needed for describing the quenched lattice data for charmonium at and above T ~ 1.1Tc ~ 350 MeV. For comparison, in the bottomonium case a good description of the lattice data is obtained with a spectral function containing a single thermally broadened resonance peak.
