   Modified combinant analysis of the $e^{+}{e}^{-}$ multiplicity distributions

   H.W.Ang🇸🇬 · M.Ghaffar🇨🇦 · A.H.Chan🇸🇬 · M.Rybczyński🇵🇱 · G.Wilk🇵🇱 · Z.Włodarczyk🇵🇱

   As shown recently, one can obtain additional information from the measured multiplicity distributions, $P(N)$, by extracting the so-called modified combinants, $C_j$. This information is encoded in their specific oscillatory behavior, which can be described only by some combinations of compound distributions, the basic part of which is the Binomial Distribution. So far this idea was applied to $pp$ and $p\bar{p}$ processes; in this note we show that an even stronger effect is observed in the $C_j$ deduced from $e^{+}{e}^{-}$ collisions. We present its possible explanation in terms of the so called Generalised Multiplicity Distribution (GMD) proposed some time ago.

   Extreme matter in electromagnetic fields and rotation

   Kenji Fukushima🇯🇵

   We look over recent developments on our understanding about relativistic matter under external electromagnetic fields and mechanical rotation. I review various calculational approaches for concrete physics problems, putting my special emphasis on generality of the method and the consequence, rather than going into phenomenological applications in a specific field of physics. The topics covered in this article include static problems with magnetic fields, dynamical problems with electromagnetic fields, and phenomena induced by rotation.

   A Possibility of Lorentz Violation in the Higgs Sector

   Satoshi Iso🇯🇵 · Noriaki Kitazawa🇯🇵

   In string theory, a scalar field often appears as a moduli of a geometrical configuration of D-branes in higher dimensional space. In the low energy effective theory on D-branes, the distance between D-branes is translated into the energy scale of the gauge symmetry breaking. In this paper, we study a phenomenological consequence of a possibility that the Higgs field is such a moduli field and the D-brane configuration is stabilized by a stationary motion, in particular, revolution of D-branes on which we live. Then, due to the Coriolis force, Higgs mode is mixed with the angular fluctuation of branes and the Lorentz symmetry is violated in the dispersion relation of the Higgs boson. The Higgs boson mass measurements at LHC experiments give an upper bound $\sim \mathcal{O}(0.1)$ GeV for the angular frequency of the revolution of D-branes.

   FCC-he sensitivity estimates on the anomalous electromagnetic dipole moments of the top-quark

   M. A. Hernández-Ruíz🇲🇽 · A. Gutiérrez-Rodríguez🇲🇽 · M. Köksal🇹🇷 · A. A. Billur🇹🇷

   In this paper, we study the production of a top-quark in association with a bottom-quark and a electron-neutrino at the Future Circular Collider Hadron Electron (FCC-he) to probe the sensitivity on its magnetic moment $({\hat{a}}_V)$ and its electromagnetic dipole moment $({\hat{a}}_A)$ through the process $e^{-}p\to e^{-}\gamma p\to \bar{t}{\nu }_{e}bp$. Assuming a large amount of collisions, as well as of data with cleaner environments, the FCC-he is an excellent option to study new physics, such as the ${\hat{a}}_V$ and ${\hat{a}}_A$. For our sensitivity study on ${\hat{a}}_V$ and ${\hat{a}}_A$, we consider center-of-mass energies $\sqrt{s}=7.07,10TeV$ and luminosities $\mathcal{L}=50,100,300,500,1000f{b}^{-1}$. In addition, we apply systematic uncertainties ${\delta }_{sys}=0\%,3\%,5\%$ and we consider unpolarized and polarized electron beam. Our results show that the FCC-he is a very good perspective to probe the ${\hat{a}}_V$ and ${\hat{a}}_A$ at high-energy and high-luminosity frontier.

   Exotic $bc\bar{q}\bar{q}$ four-quark states

   Teresa F. Carames🇪🇸 · Javier Vijande🇪🇸 · Alfredo Valcarce🇪🇸

   We carry out a systematic study of exotic $Q{Q}^{\prime }\bar{q}\bar{q}$ four-quark states containing distinguishable heavy flavors, $b$ and $c$. Different generic constituent models are explored in an attempt to extract general conclusions. The results are robust, predicting the same sets of quantum numbers as the best candidates to lodge bound states independently of the model used, the isoscalar $J^P=0^{+}$ and $J^P=1^{+}$ states. The first state would be strong and electromagnetic-interaction stable while the second would decay electromagnetically to $\bar{B}D\gamma$. Isovector states are found to be unbound, preventing the existence of charged partners. The interest on exotic heavy-light tetraquarks with non identical heavy-flavors comes reinforced by the recent estimation of the production rate of the isoscalar $bc\bar{u}\bar{d}$ $J^P=1^{+}$ state, two orders of magnitude larger than that of the $bb\bar{u}\bar{d}$ analogous state.

   A new parton model for the soft interactions at high energies

   E. Gotsman (Tel Aviv U.)🇮🇱 · E. Levin (Tel Aviv U./UTFSM)🇮🇱 · I. Potashnikova (UTFSM)🇨🇱

   We propose a new parton model and demonstrate that the model describes the relevant experimental data at high energies. The model is based on Pomeron calculus in 1+1 space-time dimensions, as suggested in Ref. [18] and on simple assumptions regarding the hadron structure, related to the impact parameter dependence of the scattering amplitude. This parton model evolves from QCD, assuming that the unknown non-perturbative corrections lead to fixing size of the interacting dipoles. The advantage of this approach is that it satisfies both t-channel and s-channel unitarity, and can be used for summing all diagrams of Pomeron interactions, including Pomeron loops. We can use this approach for all reactions: dilute-dilute (hadron-hadron), dilute-dense (hadron-nucleus) and dense-dense (nucleus-nucleus)for the scattering of parton systems. Unfortunately, we are still far from being able to tackle this problem in the effective QCD theory at high energy (i.e. in the CGC /saturation approach).

   Any Room Left for Technicolor? Dilepton Searches at the LHC and Beyond

   Alexander Belyaev · Azaria Coupe · Nick Evans · Marc Scott

   Precision electroweak data, a light higgs and LHC searches for new spin one particles are all very constraining on technicolor models. We use a holographic model of walking techicolor (WTC) gauge dynamics, tuned to produce a light higgs and low $S$ parameter, to estimate the range of possible vector($\rho$) and pseudo-vector($A$) resonance masses and couplings as a function of the number of colours and the number of flavours of techni-singlet and techni-doublet quarks. The resulting models predict techni-hadron masses and couplings above the current limits from dilepton resonance searches at the LHC because their masses are enhanced by the strong coupling extending into the multi-TeV range, while couplings to Standard Model fermions are partly suppressed. The models emphasize the contortions needed to continue to realize technicolor, {the need to explore new signatures beyond dilepton for LHC and also motivate a 100 TeV proton collider.

   Nuclear Uncertainties in the Determination of Proton PDFs

   Richard D. Ball🇬🇧 · Emanuele R. Nocera🇳🇱 · Rosalyn L. Pearson🇬🇧

   We show how theoretical uncertainties due to nuclear effects may be incorporated into global fits of proton parton distribution functions (PDFs) that include deep-inelastic scattering and Drell-Yan data on nuclear targets. We specifically consider the CHORUS, NuTeV and E605 data included in the NNPDF3.1 fit, which used Pb, Fe and Cu targets, respectively. We show that the additional uncertainty in the proton PDFs due to nuclear effects is small, as expected, and in particular that the effect on the $\bar{d}/\bar{u}$ ratio, the total strangeness $s+\bar{s}$, and the strange valence distribution $s-\bar{s}$ is negligible.

   Transverse momentum dependence in double parton scattering

   Jonathan R. Gaunt🇨🇭 · Tomas Kasemets🇩🇪

   In this review, we describe the status of transverse momentum dependence (TMD) in double parton scattering (DPS). The different regions of TMD DPS are discussed, and expressions given for the DPS cross section contributions that make use of as much perturbative information as possible. The regions are then combined with each other as well as with single parton scattering to obtain a complete expression for the cross section. Particular emphasis is put on the differences and similarities to transverse momentum dependence in single parton scattering. We further discuss the status of the factorisation proof for double colour singlet production in DPS, which is now on a similar footing to the proofs for TMD factorisation in single Drell-Yan, discuss parton correlations and give an outlook on possible research on DPS in the near future.

    Dark radiation: 21cm signals and laboratory tests

    Josef Pradler🇦🇹

    It is entirely possible that our Universe is filled with dark radiation, such as SM neutrinos or new physics states, that are sourced by the decay of dark matter with cosmologically long lifetime. If non-thermal neutrinos produced such way carry sufficient energy, they can leave a detectable imprint in experiments designed to search for very weakly interacting particles: dark matter and underground neutrino experiments. Conversely, a very soft non-thermal population of dark photons sourced this way is allowed to exceed the number density of CMB photons by many orders of magnitude without being in conflict with current bounds. Equipped with a small probability of conversion into ordinary photons, the scenario becomes testable through the cosmological 21cm signal.

    Ab initio three-loop calculation of the W-exchange contribution to nonleptonic decays of double charm baryons

    Thomas Gutsche🇩🇪 · Mikhail A. Ivanov🇷🇺 · Jürgen G. Körner🇩🇪 · Valery E. Lyubovitskij🇩🇪 · Zhomart Tyulemissov🇷🇺

    We have made an ab initio three-loop quark model calculation of the $W$-exchange contribution to the nonleptonic two-body decays of the doubly charmed baryons ${\Xi }_{cc}^{++}$ and ${\Omega }_{cc}^{+}$. The $W$-exchange contributions appear in addition to the factorizable tree graph contributions and are not suppressed in general. We make use of the covariant confined quark model previously developed by us to calculate the tree graph as well as the $W$-exchange contribution. We calculate helicity amplitudes and quantitatively compare the tree graph and $W$-exchange contributions. Finally, we compare the calculated decay widths with those from other theoretical approaches when they are available.

    Quark-Gluon Tagging: Machine Learning vs Detector

    Gregor Kasieczka🇩🇪 · Nicholas Kiefer🇩🇪 · Tilman Plehn🇩🇪 · Jennifer M. Thompson🇩🇪

    Distinguishing quarks from gluons based on low-level detector output is one of the most challenging applications of multi-variate and machine learning techniques at the LHC. We first show the performance of our 4-vector-based LoLa tagger without and after considering detector effects. We then discuss two benchmark applications, mono-jet searches with a gluon-rich signal and di-jet resonances with a quark-rich signal. In both cases an immediate benefit compared to the standard event-level analysis exists.

    LHC limits on gluinos and squarks in the minimal Dirac gaugino model

    Guillaume Chalons🇫🇷 · Mark D. Goodsell🇫🇷 · Sabine Kraml🇫🇷 · Humberto Reyes-González🇫🇷 · Sophie L. Williamson🇫🇷

    Dirac gauginos are a well-motivated extension of the MSSM, leading to interesting phenomenological consequences. At the LHC, gluino-pair production is enhanced while squark production is suppressed as compared to the MSSM, and the decay signatures are altered by a more complex chargino and neutralino spectrum. We investigate how this impacts current gluino and squark mass limits from Run~2 of the LHC. Concretely, we compare different assumptions about the electroweak-ino spectrum through four benchmark models paying particular attention to the effect of the trilinear ${\lambda }_S$ coupling, which induces a mass splitting between the mostly bino/U(1) adjoint states. Among other results, we show that for large ${\lambda }_S$ the additional ${\tilde{\chi }}_2^0\to f\bar{f}{\tilde{\chi }}_1^0$ decays somewhat weaken the limits on gluinos (squarks) in the case of heavy squarks (gluinos). Moreover, we compare the limits in the gluino vs. squark mass plane to those obtained in equivalent MSSM scenarios.

    Higgs Couplings without the Higgs

    Brian Henning🇨🇭 · Davide Lombardo🇨🇭 · Marc Riembau🇨🇭 · Francesco Riva🇨🇭

    The measurement of Higgs couplings constitute an important part of present Standard Model precision tests at colliders. In this article, we show that modifications of Higgs couplings induce energy-growing effects in specific amplitudes involving longitudinally polarized vector bosons, and we initiate a novel program to study these very modifications of Higgs couplings off-shell and at high-energy, rather than on the Higgs resonance. Our analysis suggests that these channels are complementary and, at times, competitive with familiar on-shell measurements; moreover these high-energy probes offer endless opportunities for refinements and improvements.

    Probing Generalized Parton Distributions through the photoproduction of a $\gamma \pi$ pair

    G. Duplančić🇭🇷 · K. Passek-Kumerički🇭🇷 · B. Pire🇫🇷 · L. Szymanowski🇵🇱 · S. Wallon🇫🇷

    We study in the framework of collinear QCD factorization the photoproduction of a $\gamma \pi$ pair with a large invariant mass and a small transverse momentum, as a new way to access generalized parton distributions. In the kinematics of JLab 12-GeV, we demonstrate the feasibility of this measurement and show the extreme sensitivity of the unpolarized cross section to the axial quark GPDs.

    The second Higgs at the lifetime frontier

    Samuel Alipour-fard🇺🇸 · Nathaniel Craig🇺🇸 · Stefania Gori🇺🇸 · Seth Koren🇺🇸 · Diego Redigolo🇮🇱

    We assess the current coverage and the future discovery potential of LHC searches for heavy Higgs bosons decaying into long-lived particles (LLPs), focusing primarily on the production of pairs of LLPs with hadronic final states. These signatures are generic in dark sectors where a heavy scalar decays into pairs of lighter states which subsequently mix with the Standard Model Higgs. We show that a handful of existing analyses provide broad coverage of LLP decay lengths ranging from millimeters to tens of meters, and explore the complementarity between searches for displaced and prompt final states in several simplified models. For both heavy singlet and heavy doublet scalars, LLP searches typically provide the leading sensitivity in current data and exhibit the strongest discovery potential in future LHC runs. We further translate the impact of these searches into the parameter space of various Twin Higgs models, demonstrating that LLP searches are a promising avenue for discovering a Twin Higgs with displaced decays. Finally, we propose a variety of additional search channels that would improve coverage of the second Higgs at the lifetime frontier.

    Foraging for dark matter in large volume liquid scintillator neutrino detectors with multiscatter events

    Joseph Bramante🇨🇦 · Benjamin Broerman🇨🇦 · Jason Kumar🇺🇸 · Rafael F. Lang🇺🇸 · Maxim Pospelov🇨🇦 · Nirmal Raj🇨🇦

    We show that dark matter with a per-nucleon scattering cross section $\gtrsim 10^{-28}\mathrm{c}{\mathrm{m}}^2$ could be discovered by liquid scintillator neutrino detectors like BOREXINO, SNO+, and JUNO. Due to the large dark matter fluxes admitted, these detectors could find dark matter with masses up to $10^{21}$ GeV, surpassing the mass sensitivity of current direct detection experiments (such as XENON1T and PICO) by over two orders of magnitude. We derive the spin-independent and spin-dependent cross section sensitivity of these detectors using existing selection triggers, and propose an improved trigger program that enhances this sensitivity by two orders of magnitude. We interpret these sensitivities in terms of three dark matter scenarios: (1) effective contact operators for scattering, (2) QCD-charged dark matter, and (3) a recently proposed model of Planck-mass baryon-charged dark matter. We calculate the flux attenuation of dark matter at these detectors due to the earth overburden, taking into account the earth's density profile and elemental composition, and nuclear spins.

    Collider and Gravitational Wave Complementarity in Exploring the Singlet Extension of the Standard Model

    Alexandre Alves🇧🇷 · Tathagata Ghosh🇺🇸 · Huai-Ke Guo🇺🇸 · Kuver Sinha🇺🇸 · Daniel Vagie🇺🇸

    We present a dedicated complementarity study of gravitational wave and collider measurements of the simplest extension of the Higgs sector: the singlet scalar augmented Standard Model. We study the following issues: (i) the electroweak phase transition patterns admitted by the model, and the proportion of parameter space for each pattern; (ii) the regions of parameter space that give detectable gravitational waves at future space-based detectors; and (iii) the current and future collider measurements of di-Higgs production, as well as searches for a heavy weak diboson resonance, and how these searches interplay with regions of parameter space that exhibit strong gravitational wave signals. We carefully investigate the behavior of the normalized energy released during the phase transition as a function of the model parameters, address subtle issues pertaining to the bubble wall velocity, and provide a description of different fluid velocity profiles. On the collider side, we identify the subset of points that are most promising in terms of di-Higgs and weak diboson production studies while also giving detectable signals at LISA, setting the stage for future benchmark points that can be used by both communities.

    Possible non-prompt photons in $pp$ collisions and their effects in $AA$ analyses

    Akihiko Monnai🇯🇵

    Direct photons are a powerful tool for elucidating the properties of the hot QCD matter in heavy-ion collisions. They are conventionally estimated by assuming prompt photon contributions in proton-proton collisions and thermal and prompt photon contributions in heavy-ion collisions. On the other hand, there could also be other sources of photons such as pre-equilibrium photons. I investigate prompt, pre-equilibrium and thermal photons and their effects on the direct photon $p_T$ spectra at CERN Large Hadron Collider energies.

    Flatness without CMB - the Entanglement of Spatial Curvature and Dark Energy Equation of State

    Haoting Xu🇨🇳 · Zhiqi Huang🇨🇳 · Zhenjie Liu🇨🇳 · Haitao Miao🇨🇳

    The cosmic spatial curvature parameter ${\Omega }_k$ is constrained, primarily by cosmic microwave background (CMB) data, to be very small. Observations of the cosmic distance ladder and the large scale structure can provide independent checks of the cosmic flatness. Such late-universe constraints on ${\Omega }_k$, however, are sensitive to the assumptions of the nature of dark energy. For minimally coupled scalar-field models of dark energy, the equation of state $w$ has nontrivial dependence on the cosmic spatial curvature ${\Omega }_k$ (Miao and Huang, 2018). Such dependence has not been taken into account in previous studies of future observational projects. In this paper we use the $w$ parameterization proposed by Miao and Huang, where the dependence of $w$ on ${\Omega }_k$ is encoded, and perform Fisher forecast on mock data of three benchmark projects: a WFIRST-like Type Ia supernovae survey, an EUCLID-like spectroscopic redshift survey, and an LSST-like photometric redshift survey. We find that the correlation between ${\Omega }_k$ and $w$ is primarily determined by the data rather than by the theoretical prior. We thus validate the standard approaches of treating ${\Omega }_k$ and $w$ as independent quantities.

    Technical Proposal for FASER: ForwArd Search ExpeRiment at the LHC

    FASER is a proposed small and inexpensive experiment designed to search for light, weakly-interacting particles during Run 3 of the LHC from 2021-23. Such particles may be produced in large numbers along the beam collision axis, travel for hundreds of meters without interacting, and then decay to standard model particles. To search for such events, FASER will be located 480 m downstream of the ATLAS IP in the unused service tunnel TI12 and be sensitive to particles that decay in a cylindrical volume with radius R=10 cm and length L=1.5 m. FASER will complement the LHC's existing physics program, extending its discovery potential to a host of new, light particles, with potentially far-reaching implications for particle physics and cosmology. This document describes the technical details of the FASER detector components: the magnets, the tracker, the scintillator system, and the calorimeter, as well as the trigger and readout system. The preparatory work that is needed to install and operate the detector, including civil engineering, transport, and integration with various services is also presented. The information presented includes preliminary cost estimates for the detector components and the infrastructure work, as well as a timeline for the design, construction, and installation of the experiment.

    Light-by-light-scattering contributions to the Lamb shift in light muonic atoms

    Evgeny Yu. Korzinin🇷🇺 · Valery A. Shelyuto🇷🇺 · Vladimir G. Ivanov🇷🇺 · Robert Szafron🇩🇪 · Savely G. Karshenboim🇩🇪

    We consider one-loop light-by-light-scattering contributions to the Lamb shift of the $1s,2s,2p$ states in light muonic hydrogen like atoms at $Z\le 10$. The contributions are of the order ${\alpha }^5{m}_{\mu }$ (with diverse dependence on the nuclear charge $Z$). Those include the contributions of the so-called Wichmann-Kroll potential ($\alpha (Z\alpha {)}^4{m}_{\mu }$), the virtual Delbrück scattering (${\alpha }^2(Z\alpha {)}^3{m}_{\mu }$), etc. The results are obtained in a nonrelativistic approximation. For the calculation of the virtual-Delbrück-scattering contribution, we have constructed an effective potential in the coordinate space which may be applied to other calculations in muonic atoms.

    Proton decay matrix element on the lattice with physical pion mass

    Jun-Sik Yoo🇺🇸 · Yasumichi Aoki🇯🇵 · Taku Izubuchi🇺🇸 · Sergey Syritsyn🇺🇸

    Proton decay is one of possible signatures of baryon number violation, which has to exist to explain the baryon asymmetry and the existence of nuclear matter. Proton decays must be mediated through effective low-energy baryon number violating operators made of three quarks and a lepton. We calculate matrix elements of these operators between the proton and various meson final states using the direct method. We report on preliminary results of matrix element calculation done with the 2+1 dynamical flavor domain wall fermions at the physical point for the first time.

    Emergent long-range interactions in Bose-Einstein Condensates

    Lasha Berezhiani🇩🇪 · Justin Khoury🇺🇸

    We consider a massive complex scalar field with contact interactions with a source and show that, upon Bose-Einstein condensation, there is an emergent long-range interaction between sources. This interaction becomes long-range in the limit of vanishing self-interaction between Bose-Einstein constituents. More generally, the range is given by ${\ell }^{-1}\propto \sqrt{\lambda n/m}$, with $\lambda$ being the 2-body self-interaction coupling constant, $n$ the particle number density in the condensate, and $m$ the mass of the condensed particles. Naively this may sound surprising since in $\lambda \to 0$ limit gapless excitations of the condensate have dispersion relation ${\omega }_k=k^2/2m$, yet for the mediated force we have $F\propto 1/r^2$. The reason behind this seemingly counterintuitive result lies in the fact that the force is being mediated by the phonon, which happens to acquire a nontrivial derivative interaction with the source. We discuss the potential ramifications of this observation for dark matter models. In particular, we show that this force can compete with gravity on galactic scales for a wide range of dark matter mass, provided that the interaction with baryons allows the presence of an extended dark matter condensate core. The effect could be of particular interest in ultra-light dark matter models, such as Fuzzy Dark Matter.
