   Model-independent search strategy for the lepton-flavor-violating heavy Higgs boson decay to $\tau \mu$ at the LHC

   Ernesto Arganda🇦🇷 · Xabier Marcano🇫🇷 · Nicolás I. Mileo🇦🇷 · Roberto A. Morales🇪🇸 · Alejandro Szynkman🇦🇷

   In this work we present a model-independent search strategy at the LHC for heavy Higgs bosons decaying into a tau and a muon, $H/A\to \tau \mu$, showing a plausible tendency to improve the sensitivity obtained by the present experimental limits. This search strategy is performed for the Higgs boson mass range 1-5 TeV and uses as the most relevant kinematical variables, in order to discriminate signal against background, the transverse momenta of the muon and the tau together with the missing transverse energy. We estimate the exclusion limits at 95% C.L. and the significances for evidence and discovery at $\sqrt{s}$ = 14 TeV with $\mathcal{L}$ = 300 fb${}^{-1}$, observing a growth in the sensitivities for high Higgs boson masses. Moreover, since the Higgs boson decay into a $\tau$-lepton pair may mimic our LFV signal, we also study the impact of the ditau channel on the exclusion limits and the significances for evidence and discovery. In particular, the impact on the exclusion limits of LFV heavy Higgs boson decays is significant when the ditau rate begins to compete with the corresponding to the $H/A\to \tau \mu$ decay.

   Magnetic dipole moments of the spin-$\frac{3}{2}$ doubly heavy baryons

   U. Ozdem🇹🇷

   The magnetic dipole moments of the spin-$\frac{3}{2}$ doubly charmed, bottom and charmed-bottom baryons are obtained by means of the light-cone QCD sum rule. The magnetic dipole moments of these baryons encode essential knowledge of their inner structure and shape deformations. The numerical results are given as, ${\mu }_{{\Xi }_{cc}^{\ast ++}}=2.94\pm 0.95$, ${\mu }_{{\Xi }_{cc}^{\ast +}}=-0.67\pm 0.11$, ${\mu }_{{\Omega }_{cc}^{\ast +}}=-0.52\pm 0.07$, ${\mu }_{{\Xi }_{bb}^{\ast 0}}=2.30\pm 0.55$, ${\mu }_{{\Xi }_{bb}^{\ast -}}=-1.39\pm 0.32$, ${\mu }_{{\Omega }_{bb}^{\ast -}}=-1.56\pm 0.33$, ${\mu }_{{\Xi }_{bc}^{\ast +}}=2.63\pm 0.82$, ${\mu }_{{\Xi }_{bc}^{\ast 0}}=-0.96\pm 0.32$ and ${\mu }_{{\Omega }_{bc}^{\ast +}}=-1.11\pm 0.33$, respectively.

   Testing SU(3) Flavor Symmetry in Semileptonic and Two-body Nonleptonic Decays of Hyperons

   Ru-Min Wang🇨🇳 · Mao-Zhi Yang🇨🇳 · Hai-Bo Li🇨🇳 · Xiao-Dong Cheng🇨🇳

   The semileptonic decays and two-body nonleptonic decays of light baryon octet ($T_8$) and decuplet ($T_{10}$) consisting of light $u,d,s$ quarks are studied with the SU(3) flavor symmetry in this work. We obtain the amplitude relations between different decay modes by the SU(3) irreducible representation approach, and then predict relevant branching ratios by present experimental data within $1\sigma$ error. We find that the predictions for all branching ratios except $\mathcal{B}(\Xi \to {\Lambda }^0\pi )$ and $\mathcal{B}({\Xi }^{\ast }\to \Xi \pi )$ are in good agreement with present experimental data, that implies the neglected $C_{+}$ terms or SU(3) breaking effects might contribute at the order of a few percent in $\Xi \to {\Lambda }^0\pi$ and ${\Xi }^{\ast }\to \Xi \pi$ weak decays. We predict that $\mathcal{B}({\Xi }^{-}\to {\Sigma }^0{\mu }^{-}{\bar{\nu }}_{\mu })=(1.13\pm 0.08)\times 10^{-6}$, $\mathcal{B}({\Xi }^{-}\to {\Lambda }^0{\mu }^{-}{\bar{\nu }}_{\mu })=(1.58\pm 0.04)\times 10^{-4}$, $\mathcal{B}({\Omega }^{-}\to {\Xi }^0{\mu }^{-}{\bar{\nu }}_{\mu })=(3.7\pm 1.8)\times 10^{-3}$, $\mathcal{B}({\Sigma }^{-}\to {\Sigma }^0{e}^{-}{\bar{\nu }}_e)=(1.35\pm 0.28)\times 10^{-10}$, $\mathcal{B}({\Xi }^{-}\to {\Xi }^0{e}^{-}{\bar{\nu }}_e)=(4.2\pm 2.4)\times 10^{-10}$. We also study $T_{10}\to T_8{P}_8$ weak, electromagnetic or strong decays. Some of these decay modes could be observed by the BESIII, LHCb and other experiments in the near future. Due to the very small life times of ${\Sigma }^0$, ${\Xi }^{\ast 0,-}$, ${\Sigma }^{\ast 0,-}$ and ${\Delta }^{0,-}$, the branching ratios of these baryon weak decays are only at the order of $\mathcal{O}(10^{-20}-10^{-13}$), which are too small to be reached by current experiments. Furthermore, the longitudinal branching ratios of $T_{8A}\to T_{8B}{\ell }^{-}{\bar{\nu }}_{\ell }(\ell =\mu ,e)$ decays are also given.

   Optimizing the parton shower model in PYTHIA with pp collision data at $\sqrt{s}$ = 13 TeV

   S. K. Kundu🇮🇳 · T. Sarkar🇮🇳 · M. Maity🇮🇳

   Production of quarks and gluons in hadron collisions tests Quantum Chromodynamics (QCD) over a wide range of energy. Models of QCD are implemented in event generators to simulate hadron collisions and evolution of quarks and gluons into jets of hadrons. PYTHIA8 uses the parton shower model for simulating particle collisions and is optimized using experimental observations. Recent measurements of event shape variables and jet cross-sections in pp collisions at $\sqrt{s}$ = 13 TeV at the Large Hadron Collider have been used to optimize the parton shower model as used in PYTHIA8.

   Cosmology with a Master Coupling in Flipped SU(5) $\times$ U(1): The ${\lambda }_6$ Universe

   John Ellis🇬🇧 · Marcos A. G. Garcia🇺🇸 · Natsumi Nagata🇯🇵 · Dimitri V. Nanopoulos🇺🇸 · Keith A. Olive🇺🇸

   We propose a complete cosmological scenario based on a flipped SU(5) $\times$ U(1) GUT model that incorporates Starobinsky-like inflation, taking the subsequent cosmological evolution carefully into account. A single master coupling, ${\lambda }_6$, connects the singlet, GUT Higgs and matter fields, controlling 1) inflaton decays and reheating, 2) the gravitino production rate and therefore the non-thermal abundance of the supersymmetric cold dark matter particle, 3) neutrino masses and 4) the baryon asymmetry of the Universe.

   Phenomenological predictions for pentaquark masses from fits to baryon masses

   Pontus Holma🇸🇪 · Tommy Ohlsson🇸🇪

   We investigate the mass spectra of exotic hadrons known as pentaquarks. We extend a simple phenomenological model based on the Gürsey-Radicati mass formula for hadrons to include both charmed and bottom baryons as well as to be able to predict masses of pentaquark states including both charm and bottom quark-antiquark pairs. In particular, we perform numerical fits of this model, which includes seven free parameters, to masses of 21 baryons. We find that the model can be well fitted to the experimental values of the baryon masses and observe that the predicted value of about 4400 MeV for the mass of the pentaquark $P_c(4380{)}^{+}$ lies within the experimental range reported by the LHCb experiment. In addition, the predicted value of about 4500 MeV for the mass of the pentaquark $P_c(4450{)}^{+}$ is close to the experimental value. Finally, in the future, other predicted values for masses of additional pentaquarks could be shown to agree with upcoming experimental results.

   Deciphering the $X(3872)$ via its polarization in prompt production at the CERN LHC

   Mathias Butenschoen🇩🇪 · Zhi-Guo He🇩🇪 · Bernd A. Kniehl🇩🇪

   Based on the hypothesis that the $X(3872)$ exotic hadron is a mixture of ${\chi }_{c1}(2P)$ and other states and that its prompt hadroproduction predominately proceeds via its ${\chi }_{c1}(2P)$ component, we calculate the prompt-$X(3872)$ polarization at the CERN LHC through next-to-leading order in ${\alpha }_s$ within the factorization formalism of nonrelativistic QCD, including both the color-singlet ${}^3{P}_1^{[1]}$ and color-octet ${}^3{S}_1^{[8]}$ $c\bar{c}$ Fock states. We also consider the polarization of the $J/\psi$ produced by the subsequent $X(3872)$ decay. We predict that, under ATLAS, CMS, and LHCb experimental conditions, the $X(3872)$ is largely longitudinally polarized, while the $J/\psi$ is largely transversely polarized. We propose that the LHC experiments perform such polarization measurements to pin down the nature of the $X(3872)$ and other $X$, $Y$, $Z$ exotic states with non-zero spin.

   Quasistable charginos in ultraperipheral proton-proton collisions at the LHC

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

   We propose a model-independent approach for the search of charged long-lived particles produced in ultraperipheral collisions at the LHC. The main idea is to improve event reconstruction at ATLAS and CMS with the help of their forward detectors. Detection of both scattered protons in forward detectors allows complete recovery of event kinematics. Though this requirement reduces the number of events, it greatly suppresses the background, including the large background from the pile-up.

   Global Bayesian Analysis of new physics in $b\to s\mu \mu$ transitions after Moriond-2019

   Dinesh Kumar🇵🇱 · Kamila Kowalska🇵🇱 · Enrico Maria Sessolo🇵🇱

   The recent measurement of $R_K$ at LHCb continues to support the hint of violation of lepton flavor universality. We perform a global fit for new physics in semileptonic $b\to s$ transitions using all the relevant data with a Bayesian analysis technique. We include new measurements of $R_K$ at LHCb and new determinations of $R_{K^{\ast }}$ and $R_{K^{\ast +}}$ at Belle. We perform the scan for various NP scenarios and infer the 68\% and 95.4\% credibility regions of the marginalized posterior probability density for all scenarios. We also compare the models in pairs by calculating the Bayes factor given a common data set. A few well-known BSM models are analyzed that can provide a high energy framework for the EFT analysis. These include the exchange of a heavy $Z^{{}^{\prime }}$ boson in models with heavy vector-like fermions and a scalar field, and a model with scalar leptoquarks. We provide predictions for the BSM couplings and expected mass values.

    Formulating the Kramers problem in field theory

    Arjun Berera🇬🇧 · Joel Mabillard🇬🇧 · Bruno W. Mintz🇧🇷 · Rudnei O. Ramos🇧🇷

    The escape problem is defined in the context of quantum field theory. The escape rate is explicitly derived for a scalar field governed by fluctuation-dissipation dynamics, through generalizing the standard Kramers problem. In the presence of thermal fluctuations, there is a nonvanishing probability for a classical background field, initially located at a minimum of its potential in a homogeneous configuration, to escape from the well. The simple and well-known related problem of the escape of a classical point particle due to random forces is first reviewed. We then discuss the difficulties associated with a well-defined formulation of an escape rate for a scalar field and how these can be overcome. A definition of the Kramers problem for a scalar field and a method to obtain the rate are provided. Finally, we discuss some of the potential applications of our results, which can range from condensed matter systems, i.e., nonrelativistic fields, to applications in high-energy physics, like for cosmological phase transitions.

    LHC sensitivity to singly-charged scalars decaying into electrons and muons

    Julien Alcaide🇪🇸 · Nicolás I. Mileo🇦🇷

    Current LHC searches for non-supersymmetric singly-charged scalars, based on Two-Higgs-Doublet models, in general focus the analysis on third-generation fermions in the final state. However, singly-charged scalars in alternative extensions of the scalar sector involve Yukawa couplings not proportional to the mass of the fermions. Assuming the scalar decays into electrons and muons, it can manifest cleaner experimental signatures. In this paper we suggest that a singly-charged scalar singlet, with electroweak production, can start to be probed in the near future with dedicated search strategies. Depending on the strength of the Yukawa couplings, two independent scenarios are considered: direct pair-production (small couplings) and single-production via virtual neutrino exchange (large couplings). We show that, up to a mass as large as 500 GeV, most of the parameter space could be excluded at the 95% C.L. in a high-luminosity phase of the LHC. Our results also apply to other frameworks, provided the singly-charged scalar exhibits similar production patterns and dominant decay modes.

    Renormalization Effects on Electric Dipole Moments in Electroweakly Interacting Massive Particle Models

    Takumi Kuwahara🇰🇷

    The extended models of the standard model with a single Majorana fermion could be realized as the low-energy effective theory of the well-motivated ultraviolet models. We study the electric dipole moments generated by the effective operators which are composed of the Majorana fermion and the standard model Higgs bosons, especially focusing on the renormalization effects of the effective operators. We give the one-loop anomalous dimension of the effective operators from the scale where the operators are generated to the electroweak scale. In this proceedings, we focused on the electric dipole moments from electroweak Majorana fermions, triplet and 5-plet. We found the renormalization effects could give an enhancement factor being of the order of O(10)% for a triplet model and being more than two in a 5-plet fermion model.

    Weak-U(1) x Strong-U(1) Effective Gauge Field Theories and electron-monopole scattering

    Jean Alexandre🇬🇧 · Nick E. Mavromatos🇬🇧

    We present a gauge and Lorentz invariant model for the scattering of matter off magnetic poles, which justifies the presence of velocity-dependent magnetic charges as an effective description of either the behaviour of monopoles in scattering with matter or their production from matter particles at colliders. Hence, in such an approach, perturbativity of the magnetic charge is ensured for relative low velocities of monopoles with respect to matter particles. The model employs a ${\mathrm{U}(1)}_{\mathrm{weak}}\times {\mathrm{U}(1)}_{\mathrm{strong}}$ effective gauge field theory under which electrons and monopoles (assumed to be fermions) are appropriately charged. The non-perturbative quantum effects of the strongly coupled sector of the theory lead to dressed effective couplings of the monopole/dyon with the electromagnetic photon, due to non-trivial wave-function renormalization effects. For slowly-moving monopole/dyons, such effects lead to weak coupling, thus turning the bare non-perturbative magnetic charge, which is large due to the Dirac/Schwinger quantization rule, into a perturbative effective, velocity-("$\beta$")-dependent magnetic coupling. Our work thus offers formal support to previous conjectural studies, employing effective U(1)-electromagnetic gauge field theories for the description of monopole production from Standard Model matter, which are used in contemporary collider searches of such objects. This work necessarily pertains to composite monopoles, as seems to be the case of all known monopoles so far, that are solutions of specific particle physics models. This is a consequence of the fact that the wave-function renormalization of the (slowly-moving) monopole fermion turns out to violate unitarity bounds that would characterise asymptotic elementary particle states.

    Explaining electron and muon $g-2$ anomaly in SUSY without lepton-flavor mixings

    Motoi Endo🇯🇵 · Wen Yin🇰🇷

    We propose a SUSY scenario to explain the current electron and muon $g-2$ discrepancies without introducing lepton flavor mixings. Threshold corrections to the Yukawa couplings can enhance the electron $g-2$ and flip the sign of the SUSY contributions. The mechanism predicts a flavor-dependent slepton mass spectrum. We show that it is compatible with the Higgs mediation scenario.

    Bag-type Model with Fractal Structure

    Evandro Andrade II🇧🇷 · Airton Deppman🇧🇷 · Eugenio Megias🇪🇸 · Débora P. Menezes🇧🇷 · Tiago Nunes da Silva🇧🇷

    In this work we present a bag-type model within a non-extensive statistics applied to the description of the properties of a hadronic system with an underlying fractal structure. The non-extensive ideal gas inside the bag is determined by the grand canonical partition function from which pressure, energy and particle density as well as temperature and chemical potential are obtained for the hadronic system. These quantities are studied in the approximation of fixed mass for all bag constituents but also for discrete and continuum masses. In all cases, the freeze-out line, corresponding to the energy per particle equal to 1 GeV and the lines corresponding to a fractal structure inside the proton volume are obtained. Finally, the pressure on the bag surface of the proton is calculated and the resulting value $(0.135\mathrm{GeV}{)}^4$ obtained.

    Precision measurement of the ${\Lambda }_c^{+}$, ${\Xi }_c^{+}$ and ${\Xi }_c^0$ baryon lifetimes

    We report measurements of the lifetimes of the ${\Lambda }_c^{+}$, ${\Xi }_c^{+}$ and ${\Xi }_c^0$ charm baryons using proton-proton collision data at center-of-mass energies of 7 and 8\tev, corresponding to an integrated luminosity of 3.0 fb${}^{-1}$, collected by the LHCb experiment. The charm baryons are reconstructed through the decays ${\Lambda }_c^{+}\to p{K}^{-}{\pi }^{+}$, ${\Xi }_c^{+}\to p{K}^{-}{\pi }^{+}$ and ${\Xi }_c^0\to p{K}^{-}{K}^{-}{\pi }^{+}$, and originate from semimuonic decays of beauty baryons. The lifetimes are measured relative to that of the $D^{+}$ meson, and are determined to be \begin{align*} \tau_{\Lambda_c^+} &= 203.5\pm1.0\pm1.3\pm1.4~{\rm fs}, \newline \tau_{\Xi_c^+} &= 456.8\pm3.5\pm2.9\pm3.1~{\rm fs}, \newline \tau_{\Xi_c^0} &= 154.5\pm1.7\pm1.6\pm1.0~{\rm fs}, \end{align*} where the uncertainties are statistical, systematic, and due to the uncertainty in the $D^{+}$ lifetime. The measurements are approximately 3--4 times more precise than the current world average values. The ${\Lambda }_c^{+}$ and ${\Xi }_c^{+}$ lifetimes are in agreement with previous measurements; however, the ${\Xi }_c^0$ baryon lifetime is approximately 3.3 standard deviations larger than the world average value.

    Finite-temperature Equations of State for Neutron Star Mergers

    Paul M. Chesler🇺🇸 · Niko Jokela🇫🇮 · Abraham Loeb🇺🇸 · Aleksi Vuorinen🇫🇮

    The detection of gravitational waves from a neutron star merger has opened up the possibility of detecting the presence or creation of deconfined quark matter using the gravitational wave signal. To investigate this possibility, we construct a family of neutron star matter equations of state at nonzero density and temperature by combining state-of-the-art nuclear matter equations of state with holographic equations of state for strongly interacting quark matter. The emerging picture consistently points toward a strong first order deconfinement transition, with a temperature-dependent critical density and latent heat that we quantitatively examine. Recent neutron star mass measurements are further used to discriminate between the different equations of state obtained, leaving a tightly constrained family of preferred equations of state.

    Reanalyze the pulsar scenario to explain the cosmic positron excess considering the recent developments

    Kun Fang🇨🇳 · Xiao-Jun Bi🇨🇳 · Peng-Fei Yin🇨🇳

    As the TeV halos around Geminga and PSR B0656+14 have been confirmed by HAWC, slow diffusion of cosmic rays could be general around pulsars, and the cosmic positron spectrum from pulsars could be significantly changed. As a consequence, the most likely pulsar source of the positron excess, Geminga, is no more a viable candidate under the additional constraint from Fermi-LAT. Moreover, the latest measurement by AMS-02 shows a clear cutoff in the positron spectrum, which sets a strict constraint on the age of the pulsar source. Considering these new developments we reanalyze the scenario in this work. By checking all the observed pulsars under the two-zone diffusion scenario, we propose for the first time that PSR B1055-52 is a very promising source of the positron excess. B1055-52 can well reproduce both the intensity and the high-energy cut of the AMS-02 positron spectrum, and may also explain the H.E.S.S $e^{-}+e^{+}$ spectrum around 10 TeV. Moreover, if the slow diffusion is universal in the local interstellar medium, B1055-52 will be the unique reasonable source of the AMS-02 positron spectrum among the observed pulsars.

    Exotic quarkonium physics prospects at Belle II

    J. V. Bennett🇺🇸

    The Belle II experiment at the SuperKEKB energy-asymmetric $e^{+}{e}^{-}$ collider is a substantial upgrade of the B factory facility at KEK in Tsukuba, Japan. It aims to record a factor of 50 times more data than its predecessor. The experiment completed a commissioning run in 2018, and began full operation in early 2019. Belle II is uniquely capable of studying the so-called XYZ particles: heavy exotic hadrons consisting of more than three quarks. First discovered by Belle, these now number in the dozens, and represent the emergence of a new category within quantum chromodynamics. This talk will present the prospects of Belle II to explore exotic quarkonium physics.

    Time-sliced perturbation theory with primordial non-Gaussianity and effects of large bulk flows on inflationary oscillating features

    Anagha Vasudevan🇩🇰 · Mikhail M. Ivanov🇺🇸 · Sergey Sibiryakov🇨🇭 · Julien Lesgourgues🇩🇪

    We extend the formalism of time-sliced perturbation theory (TSPT) for cosmological large-scale structure to include non-Gaussian initial conditions. We show that in such a case the TSPT interaction vertices acquire new contributions whose time-dependence factorizes for the Einstein-de Sitter cosmology. The new formulation is free from spurious infrared (IR) enhancements and reveals a clear IR structure of non-Gaussian vertices. We use the new technique to study the evolution of oscillating features in primordial statistics and show that they are damped due to non-linear effects of large bulk flows. We derive the damping factors for the oscillating primordial power spectrum and bispectrum by means of a systematic IR resummation of relevant Feynman diagrams.

    Primordial Features from Linear to Nonlinear Scales

    Florian Beutler🇬🇧 · Matteo Biagetti🇳🇱 · Daniel Green🇺🇸 · Anže Slosar🇺🇸 · Benjamin Wallisch🇺🇸

    Sharp features in the primordial power spectrum are a powerful window into the inflationary epoch. To date, the cosmic microwave background (CMB) has offered the most sensitive avenue to search for these signatures. In this paper, we demonstrate the power of large-scale structure observations to surpass the CMB as a probe of primordial features. We show that the signatures in galaxy surveys can be separated from the broadband power spectrum and are as robust to the nonlinear evolution of matter as the standard baryon acoustic oscillations. As a result, analyses can exploit a significant range of scales beyond the linear regime available in the datasets. We develop a feature search for large-scale structure, apply it to the final data release of the Baryon Oscillation Spectroscopic Survey and find new bounds on oscillatory features that exceed the sensitivity of Planck for a significant range of frequencies. Moreover, we forecast that the next generation of galaxy surveys, such as DESI and Euclid, will be able to improve current constraints by up to an order of magnitude over an expanded frequency range.
