   Probing a slepton Higgs on all frontiers

   Carla Biggio🇮🇹 · Jeff Asaf Dror🇺🇸 · Yuval Grossman🇺🇸 · Wee Hao Ng🇺🇸

   We study several aspects of supersymmetric models with a $U(1{)}_R$ symmetry where the Higgs doublet is identified with the superpartner of a lepton. We derive new, stronger bounds on the gaugino masses based on current measurements, and also propose ways to probe the model up to scales of $\mathcal{O}(10\text{TeV})$ at future $e^{+}{e}^{-}$ colliders. Since the $U(1{)}_R$ symmetry cannot be exact, we analyze the effects of $R$-symmetry breaking on neutrino masses and proton decay. In particular, we find that getting the neutrino mixing angles to agree with experiments in a minimal model requires a UV cutoff for the theory at around $10\text{ TeV}$.

   Study on the rare decays of $Y(4630)$ induced by final state interactions

   Xing-Dao Guo🇨🇳 · Dian-Yong Chen🇨🇳 · Hong-Wei Ke🇨🇳 · Xiang Liu🇨🇳 · Xue-Qian Li🇨🇳

   A resonance $Y(4630)$ at the invariant mass spectrum of ${\Lambda }_c{\bar{\Lambda }}_c$ observed by the Belle Collaboration triggers a hot discussion about its inner structure. Since it preferably decays into two charmed baryons ${\Lambda }_c{\bar{\Lambda }}_c$, it is tempted to conjecture it as a tetraquark. Because the dominant decay portal $Y(4630)\to {\Lambda }_c{\bar{\Lambda }}_c$ is close to the energy threshold, the final state interactions may be significant and result in other baryonic and/or mesonic final states whose branching fractions are sizable to be measured in the future experiments. In this work we calculate the branching ratios of the $Y(4630)$ decays into $p\bar{p}$, $D^{(\ast )+}{D}^{(\ast )-}$, ${\pi }^{+}{\pi }^{-}$, and $K^{+}{K}^{-}$ which are induced by the ${\Lambda }_c{\bar{\Lambda }}_c$ re-scattering. The resultant decay patterns will be tested by the future experiments and the consistency degree with the data composes a valuable probe for the tetraquark conjecture.

   Lepton flavour violating decays of $\mu$ and $\tau$ lepton in a gauge group $S{U}_L(2)\times S{U}_R(2)\times S{U}_l(2)$

   Fayyazuddin🇵🇰

   The electroweak unification group $SU(2{)}_L\times SU(2{)}_R\times SU(2{)}_Y$ is proposed for the charged lepton flavor violating decays of the muon ($\mu$) and tau ($\tau$) leptons. The group $SU(2{)}_Y$ is in the lepton space. The left-handed leptons and anti-leptons are assigned to the fundamental representation $(2,2,\bar{2})$ of the semi-simple group. The gauge group $SU(2{)}_Y$ is spontaneously broken to $U(1{)}_{Y_1}$, where $Y_1=-L=\pm 1$ is the hypercharge, by introducing a scalar multiplet $\Sigma$ which belongs to the triplet representation 3 of the $SU(2{)}_Y$ and is singlet under $SU(2{)}_L\times SU(2{)}_R$. At this stage charged vector bosons $Y^{\pm }$ of $SU(2{)}_Y$ which mediate the lepton flavor violating decays acquire masses and are decoupled with one Higgs scalar $H_{\Sigma }^0$. The residual group $SU(2{)}_L\times SU(2{)}_R\times U(1{)}_{Y_1}$ has all the features of the left-right electroweak unification group extensively studied in the literature. The probability for lepton flavor violating decays is ${\left(\frac{{\sin }^2{\theta }_W}{1-2{\sin }^2{\theta }_W}\right)}^2{\left(\frac{m_{W_L}}{m_Y}\right)}^4$.

   Yang-Mills Theories at High-Energy Accelerators

   George Sterman🇺🇸

   I'll begin with a brief review of the triumph of Yang-Mills theory at particle accelerators, a development that began some years after their historic paper. This story reached a culmination, or at least local extremum, with the discovery at the Large Hadron Collider of a Higgs-like scalar boson in 2012. The talk then proceeds to a slightly more technical level, discussing how we derive predictions from the gauge field theories of the Standard Model and its extensions for use at high energy accelerators.

   Analytic Bethe-Salpeter Description of the Lightest Pseudoscalar Mesons

   Wolfgang Lucha🇦🇹 · Franz F. Schöberl🇦🇹

   Within the Bethe-Salpeter formalism for instantaneous interactions, we describe, along a totally analytic route, the lightest pseudoscalar mesons by quark-antiquark bound states which show at least three indispensable general features, namely, the (almost) masslessness required for pions and kaons to be interpretable as (pseudo) Goldstone bosons, the suitable asymptotic behaviour in the limit of large spacelike relative momenta as determined by the relationship between quark mass function and Bethe-Salpeter amplitudes, and a pointwise behaviour for finite spacelike relative momenta suited for guaranteeing colour confinement.

   New Physics at 1 TeV?

   S. I. Godunov🇷🇺 · A. N. Rozanov🇫🇷 · M. I. Vysotsky🇷🇺 · E. V. Zhemchugov🇷🇺

   If decays of a heavy particle S are responsible for the diphoton excess with invariant mass 750 GeV observed at the 13 TeV LHC run, it can be easily accomodated in the Standard Model. Two scenarios are considered: production in gluon fusion through a loop of heavy isosinglet quark(s) and production in photon fusion through a loop of heavy isosinglet leptons. In the second case many heavy leptons are needed or/and they should have large electric charges in order to reproduce experimental data on $\sigma (pp\to SX)\cdot \mathrm{Br}(S\to \gamma \gamma )$.

   Asymmetries in $B\to K^{\ast }{\ell }^{+}{\ell }^{-}$ Decays and Two Higgs Doublet Model

   Ishtiaq Ahmed🇵🇰 · M. Jamil Aslam🇵🇰 · M. Ali Paracha🇵🇰

   The study of polarized branching ratio and different lepton polarization asymmeteries in the exclusive rare decays $B\to K^{\ast }{\ell }^{+}{\ell }^{-}$ ($\ell =\mu ,\tau$) have been made in the standard model (SM) and in type III of the THDM. It has been found that the effects arise from the THDM are quite promising in the longitudinal and transverse polarized branching ratios $({\mathcal{B}}_{L,T})$. Likewise, in case of $\mu$'s as final state leptons, the polarized branching ratios have an order of magnitude difference from their SM results. Similar trends have also been observed both in the longitudinal and normal lepton polarization asymmetries $P_{L,N}$ as well as their average values. We hope that the possible signatures of these observables in $B\to K^{\ast }{\ell }^{+}{\ell }^{-}$ decays at different on going and future experiments will serve as a good tool in the indirect searches of an extra Higgs boson doublet.

   QCD sum rule study of hidden-charm pentaquarks

   Hua-Xing Chen · Er-Liang Cui🇨🇳 · Wei Chen · T. G. Steele🇨🇦 · Xiang Liu🇨🇳 · Shi-Lin Zhu🇨🇳

   We study the mass spectra of hidden-charm pentaquarks having spin $J=\frac{1}{2}/\frac{3}{2}/\frac{5}{2}$ and quark contents $uudc\bar{c}$. We systematically construct all the relevant local hidden-charm pentaquark currents, and select some of them to perform QCD sum rule analyses. We find that the $P_c(4380)$ and $P_c(4450)$ can be identified as hidden-charm pentaquark states composed of an anti-charmed meson and a charmed baryon. Besides them, we also find a) the lowest-lying hidden-charm pentaquark state of $J^P=1/2^{-}$ has the mass $4.33_{-0.13}^{+0.17}$ GeV, while the one of $J^P=1/2^{+}$ is significantly higher, that is around $4.7-4.9$ GeV; b) the lowest-lying hidden-charm pentaquark state of $J^P=3/2^{-}$ has the mass $4.37_{-0.13}^{+0.18}$ GeV, consistent with the $P_c(4380)$ of $J^P=3/2^{-}$, while the one of $J^P=3/2^{+}$ is also significantly higher, that is above $4.6$ GeV; c) the hidden-charm pentaquark state of $J^P=5/2^{-}$ has a mass around $4.5-4.6$ GeV, slightly larger than the $P_c(4450)$ of $J^P=5/2^{+}$.

   Nuclear effects in deep inelastic scattering and transition region

   S. Kumano (KEK/J-PARC)🇯🇵

   We discuss nuclear effects on neutrino-nuclear interactions in a wide kinematical range from shallow to deep inelastic scattering (DIS) region. There is necessity from neutrino communities to have precise neutrino-nucleus cross sections for future measurements on neutrino oscillations and leptonic CP violation. We try to create a model to calculate neutrino cross sections in the wide kinematical range, from quasi-elastic scattering and resonance productions to the DIS. In this article, nuclear modifications of structure functions are mainly discussed, and a possible extension to the $Q^2\to 0$ region is explained. We also comment on the transition region between baryon resonances and the DIS. There are ongoing experimental efforts on nuclear modifications of structure functions or parton distribution functions such as by pA reactions at RHIC and LHC, Drell-Yan measurements at Fermilab, Miner$\nu$a neutrino DIS, and charged-lepton DIS at JLab.

    On a Possible Stationary Point in High-Energy Scattering

    V.A. Petrov🇷🇺 · A.P. Samokhin🇷🇺

    We discuss a curious observation: at energies from the ISR and up to the LHC, inclusively, the differential cross-section of elastic proton-proton scattering remains almost energy-independent at the transferred momentum t =-0.21 GeV^2 at the level of 7,5 mb/GeV^2.The latter value can be considered as a prediction for dsigma/dt at 13 TeV. We also obtain a lower bound for the forward pp slope at 13 GeV.

    Nonlinear single Compton scattering of an electron wave-packet

    A. Angioi🇩🇪 · F. Mackenroth🇩🇪 · A. Di Piazza🇩🇪

    Nonlinear single Compton scattering has been thoroughly investigated in the literature under the assumption that initially the electron has a definite momentum. Here, we study a more general initial state, and consider the electron as a wave-packet. In particular, we investigate the energy spectrum of the emitted radiation and show that in typical experimental situations some features of the spectra shown in previous works are almost completely washed out. Moreover, we show that at comparable relative uncertainties, the one in the momentum of the incoming electron has a larger impact on the photon spectra at a fixed observation direction than the one on the laser frequency.

We review and update the status of 2-body lepton- and quark-flavor violating decays involving the Higgs boson. We also comment on the possibility of observing 3-body flavor-violating Higgs decays in this context.

    Additional Information on Heavy Quark Parameters from Charged Lepton Forward-Backward Asymmetry

    Sascha Turczyk🇩🇪

    The determination of $|V_{cb}|$ using inclusive and exclusive (semi-)leptonic decays exhibits a long-standing tension of varying $\mathcal{O}(3\sigma )$ significance. For the inclusive determination the decay rate is expanded in $1/m_b$ using heavy quark expansion, and from moments of physical observables the higher order heavy quark parameters are extracted from experimental data in order to assess $|V_{cb}|$ from the normalisation. The drawbacks are high correlations both theoretically as well as experimentally among these observables. We will scrutinise the inclusive determination in order to add a new and less correlated observable. This observable is related to the decay angle of the charged lepton and can help to constrain the important heavy quark parameters in a new way. It may validate the current seemingly stable extraction of $|V_{cb}|$ from inclusive decays or hints to possible issues, and even may be sensitive to New Physics operators.

    Leptogenesis in supersymmetry with one $L$ violating coupling

    Rathin Adhikari🇮🇳 · Arnab Dasgupta🇮🇳

    We have shown a new scenario of successful leptogenesis with one $L$ violating coupling and a relative Majorana phase playing the role of $CP$ violation. This is in contrast to the usual consideration of Feynman diagram with at least two $L$ violating couplings. We have considered $R$-parity violating Minimal Supersymmetric Standard Model (MSSM) for leptogenesis at TeV scale. This scenario is also consistent with generating light neutrino mass if asymmetry is generated through semileptonic ${\lambda }^{\prime }$ coupling.

    The topological structures in strongly coupled QGP with chiral fermions on the lattice

    Sayantan Sharma🇺🇸 · Viktor Dick🇩🇪 · Frithjof Karsch🇩🇪 · Edwin Laermann🇩🇪 · Swagato Mukherjee🇺🇸

    The nature of chiral phase transition for two flavor QCD is an interesting but unresolved problem. One of the most intriguing issues is whether or not the anomalous U(1) symmetry in the flavor sector is effectively restored along with the chiral symmetry. This may determine the universality class of the chiral phase transition. Since the physics near the chiral phase transition is essentially non-perturbative, we employ first principles lattice techniques to address this issue. We use overlap fermions, which have exact chiral symmetry on the lattice, to probe the anomalous U(1) symmetry violation of 2+1 flavor dynamical QCD configurations with domain wall fermions. The latter also optimally preserves chiral and flavor symmetries on the lattice, since it is known that the remnant chiral symmetry of the light quarks influences the scaling of the chiral condensate in the crossover transition region. We observe that the anomalous U(1) is not effectively restored in the chiral crossover region. We perform a systematic study of the finite size and cut-off effects since the signals of U(1) violation are sensitive to it. We also provide a glimpse of the microscopic topological structures of the QCD medium that are responsible for the strongly interacting nature of the quark gluon plasma phase. We study the effect of these microscopic constituents through our first calculations for the topological susceptibility of QCD at finite temperature, which could be a crucial input for the equation of state for anomalous hydrodynamics.

    On Unification of Gravity and Gauge Interactions

    Ali H. Chamseddine🇱🇧 · Viatcheslav Mukhanov🇩🇪

    Considering a higher dimensional Lorentz group as the tangent symmetry, we unify gravity and gauge interactions in a natural way. The spin connection of the gauged Lorentz group is then responsible for both gravity and gauge fields, and the action for the gauged fields becomes part of the spin curvature squared. The realistic group which unifies all known particles and interactions is the $SO(1,13)$ Lorentz group whose gauge part leads to $SO(10)$ grand unified theory and contains double the number of required fermions in the fundamental spinor representation. Mirror fermions could acquire mass utilizing a mechanism employed for topological superconductors. Family unification could be achieved by considering the $SO(1,21)$ Lorentz group.

    Analysis of the observed and intrinsic durations of gamma-ray bursts with known redshift

    Mariusz Tarnopolski🇵🇱

    The duration distribution of 408 GRBs with measured both duration $T_{90}$ and redshift $z$ is examined. Mixtures of a number of distributions (standard normal, skew-normal, sinh-arcsinh, and alpha-skew-normal) are fitted to the observed and intrinsic durations using the maximum log-likelihood method. The best fit is chosen via the Akaike information critetion. The aim of this work is to assess the presence of the presumed intermediate GRB class, and to provide a phenomenological model more appropriate than the common mixture of standard Gaussians. While $\log T_{90}^{obs}$ are well described by a truly trimodal fit, after moving to the rest frame the statistically most significant fit is unimodal. To trace the source of this discrepancy, 334 GRBs observed only by $Swift$/BAT are examined in the same way. In the observer frame, this results in a number of statistically plausible descriptions, being uni- and bimodal, and with the number of components ranging from one to three. After moving to the rest frame, no unambiguous conclusions may be put forward. It is concluded that the size of the sample is not big enough to infer reliably GRB properties based on a univariate statistical reasoning only.

    Black Hole Based Tests of General Relativity

    Kent Yagi🇺🇸 · Leo C. Stein🇺🇸

    General relativity has passed all solar system experiments and neutron star based tests, such as binary pulsar observations, with flying colors. A more exotic arena for testing general relativity is in systems that contain one or more black holes. Black holes are the most compact objects in the universe, providing probes of the strongest-possible gravitational fields. We are motivated to study strong-field gravity since many theories give large deviations from general relativity only at large field strengths, while recovering the weak-field behavior. In this article, we review how one can probe general relativity and various alternative theories of gravity by using electromagnetic waves from a black hole with an accretion disk, and gravitational waves from black hole binaries. We first review model-independent ways of testing gravity with electromagnetic/gravitational waves from a black hole system. We then focus on selected examples of theories that extend general relativity in rather simple ways. Some important characteristics of general relativity include (but are not limited to) (i) only tensor gravitational degrees of freedom, (ii) the graviton is massless, (iii) no quadratic or higher curvatures in the action, and (iv) the theory is 4 dimensional. Altering a characteristic leads to a different extension of general relativity: (i) scalar-tensor theories, (ii) massive gravity theories, (iii) quadratic gravity, and (iv) theories with large extra dimensions. Within each theory, we describe black hole solutions, their properties, and current and projected constraints on each theory using black hole-based tests of gravity. We close this review by listing some of the open problems in model-independent tests and within each specific theory.

    Super-renormalizable or Finite Lee-Wick Quantum Gravity

    Leonardo Modesto🇨🇳

    We propose a class of multidimensional higher derivative theories of gravity without extra real degrees of freedom besides the graviton field. The propagator shows up the usual real graviton pole and extra complex conjugates poles that do not contribute to the absorptive part of the physical scattering amplitudes. Indeed, they may consistently be excluded from the asymptotic observable states of the theory making use of the Lee-Wick and Cutkoski, Landshoff, Olive and Polkinghorne prescription for the construction of a unitary S-matrix. Therefore, the spectrum consists on the graviton and short lived elementary unstable particles that we named "anti-gravitons" because of their repulsive contribution to the gravitational potential at short distance. However, another interpretation of the complex conjugate pairs is proposed based on the Calmet's suggestion, i.e. they could be understood as black hole precursors long established in the classical theory. Since the theory is CPT invariant, the complex conjugate of the micro black hole precursor has received as a white hole precursor consistently with the t'Hooft complementary principle. It is proved that the quantum theory is super-renormalizable in even dimension, i.e. only a finite number of divergent diagrams survive, and finite in odd dimension. Furthermore, turning on a local potential of the Riemann tensor we can make the theory finite in any dimension. The singularity-free Newtonian gravitational potential is explicitly computed for a range of higher derivative theories. Finally, we propose a new super-reneromalizable or finite Lee-Wick standard model of particle physics.

    Solving the small-scale structure puzzles with dissipative dark matter

    Robert Foot🇦🇺 · Sunny Vagnozzi🇸🇪

    Small-scale structure is studied in the context of dissipative dark matter, arising for instance in models with a hidden unbroken Abelian sector, so that dark matter couples to a massless dark photon. The dark sector interacts with ordinary matter via gravity and photon-dark photon kinetic mixing. Mirror dark matter is a theoretically constrained special case where all parameters are fixed except for the kinetic mixing strength, $ϵ$. In these models, the dark matter halo around spiral and irregular galaxies takes the form of a dissipative plasma which evolves in response to various heating and cooling processes. It has been argued previously that such dynamics can account for the inferred cored density profiles of galaxies and other related structural features. Here we focus on the apparent deficit of nearby small galaxies ("missing satellite problem"), which these dissipative models have the potential to address through small-scale power suppression by acoustic and diffusion damping. Using a variant of the extended Press-Schechter formalism, we evaluate the halo mass function for the special case of mirror dark matter. Considering a simplified model where $M_{\text{baryons}}\propto M_{\text{halo}}$, we relate the halo mass function to more directly observable quantities, and find that for $ϵ/10^{-10}\approx 2$ such a simplified description is compatible with the measured galaxy luminosity and velocity functions. On scales $M_{\text{halo}}\lesssim 10^8{M}_{\odot }$, diffusion damping exponentially suppresses the halo mass function, suggesting a nonprimordial origin for dwarf spheroidal satellite galaxies, which we speculate were formed via a top-down fragmentation process as the result of nonlinear dissipative collapse of larger density perturbation. This could explain the planar orientation of satellite galaxies around Andromeda and the Milky Way.

    BPS pion domain walls in the supersymmetric chiral Lagrangian

    Sven Bjarke Gudnason🇨🇳 · Muneto Nitta🇯🇵 · Shin Sasaki🇯🇵

    We construct exact solutions of BPS pion domain walls in the four-dimensional $\mathcal{N}=1$ supersymmetric SU(N) chiral Lagrangian with pion masses introduced via linear and quadratic superpotentials. The model admits N discrete vacua in the center of SU(N) for the linear superpotential. In addition to the latter, new vacua appear for the quadratic superpotential. We find that the domain wall solutions of pions (Nambu-Goldstone bosons) that interpolate between a pair of (pion) vacua preserve half of supersymmetry. Contrary to our expectations, we have not been able to find domain walls involving the quasi-Nambu-Goldstone bosons present in the theory, which in turn has the consequence that not all vacua of the theory are connected by a BPS domain wall solution.

    BMS in Cosmology

    Alex Kehagias🇬🇷 · Antonio Riotto🇨🇭

    Symmetries play an interesting role in cosmology. They are useful in characterizing the cosmological perturbations generated during inflation and lead to consistency relations involving the soft limit of the statistical correlators of large-scale structure dark matter and galaxies overdensities. On the other hand, in observational cosmology the carriers of the information about these large-scale statistical distributions are light rays traveling on null geodesics. Motivated by this simple consideration, we study the structure of null infinity and the associated BMS symmetry in a cosmological setting. For decelerating Friedmann-Robertson-Walker backgrounds, for which future null infinity exists, we find that the BMS transformations which leaves the asymptotic metric invariant to leading order. Contrary to the asymptotic flat case, the BMS transformations in cosmology generate Goldstone modes corresponding to both scalar and tensor degrees of freedom which may exist at null infinity and perturb the asymptotic data. Therefore, BMS transformations generate physically inequivalent vacua as they populate the universe at null infinity with these physical degrees of freedom. We also discuss the gravitational memory effect when cosmological expansion is taken into account. In this case, there are extra contribution to the gravitational memory due to the tail of the retarded Green functions which are supported not only on the light-cone, but also in its interior. The gravitational memory effect can be understood also from an asymptotic point of view as a transition among cosmological BMS-related vacua.
