   Universal relations between nongaussian fluctuations in heavy-ion collisions

   Jiunn-Wei Chen🇹🇼 · Jian Deng🇨🇳 · Hiroaki Kohyama🇹🇼 · Lance Labun🇺🇸

   We show that universality near a critical end point implies a characteristic relation between third- and fourth-order baryon susceptibilities ${\chi }_3$ and ${\chi }_4$, resulting in a banana-shaped loop when ${\chi }_4$ is plotted as a function of ${\chi }_3$ along a freeze-out line. Including the individual enhancements of ${\chi }_3$ and ${\chi }_4$ near a critical point, these features may be a consistent set of observations supporting the interpretation of baryon fluctuations data as arising from criticality.

   Jet effects in high-multiplicity pp events

   Antonio Ortiz🇲🇽 · Gyula Bencédi🇲🇽 · Héctor Bello🇲🇽 · Satyajit Jena🇺🇸

   The study of the high-multiplicity pp events has become important because we need to understand the origin of the fluid-like features which have been found in such small systems. In this work we concentrate on the radial flow signatures. To this end, the role of jets in high-multiplicity pp collisions is investigated using PYTHIA 8.

   LHC constraints and prospects for $S_1$ scalar leptoquark explaining the $\bar{B}\to D^{(\ast )}\tau \bar{\nu }$ anomaly

   Béranger Dumont🇰🇷 · Kenji Nishiwaki🇰🇷 · Ryoutaro Watanabe🇰🇷

   Recently, deviations in flavor observables of B -> D(*) tau nu have been shown between the predictions in the Standard Model and the experimental results reported by BaBar, Belle, and LHCb collaborations. One of the solutions to this anomaly is obtained in a class of leptoquark model with a scalar leptoquark boson S_1, which is a SU(3)_c triplet and SU(2)_L singlet particle with -1/3 hypercharge interacting with a quark-lepton pair. With well-adjusted couplings, this model can explain the anomaly and be compatible with all flavor constraints. In such a case, the S_1 boson can be pair-produced at CERN's Large Hadron Collider (LHC) and subsequently decay as S_1 -> t tau, b nu, c tau. This paper explores the current 8 and 13 TeV constraints, as well as the detailed prospects at 14 TeV, of this flavor-motivated S_1 model. From the current available 8 and 13 TeV LHC searches, we obtain constraints on the S_1 boson mass for M_{S_1} < 400 GeV - 640 GeV depending on values of the leptoquark couplings to fermions. Then we study future prospects for this scenario at the 14 TeV LHC using detailed cut analyses and evaluate exclusion/discovery potentials for the flavor-motivated S_1 leptoquark model from searches for the (b nu) (b nu) and (c tau) (c tau) final states. In the latter case, we consider several scenarios for the identification of charm jets. As a result, we find that the S_1 leptoquark origin of the B -> D(*) tau nu anomaly can be probed with mass less than around 600/800 GeV at the 14 TeV LHC with 300/3000 fb^-1 of accumulated data.

   The 750 GeV diphoton resonance as an sgoldstino: a reappraisal

   Debjyoti Bardhan🇮🇳 · Pritibhajan Byakti🇮🇳 · Diptimoy Ghosh🇮🇱 · Tarun Sharma🇮🇱

   Among the various explanations of the possible 750 GeV diphoton resonance, the possibility of it being an sgoldstino is an attractive one, as it is related to the spontaneous breaking of global supersymmetry. We discuss this possibility in this paper and point out the various theoretical issues associated with it. In particular, we indicate the difficulties of this explanation in realistic models of gauge mediated supersymmetry breaking.

   Unitarity methods for Mellin moments of Drell-Yan cross sections

   Domenico Bonocore🇳🇱 · Eric Laenen🇳🇱 · Robbert Rietkerk🇳🇱

   We develop a method for computing Mellin moments of single inclusive cross sections such as Drell-Yan production directly from forward scattering diagrams, by invoking unitarity in the form of cutting equations. We provide a diagram-independent prescription for eliminating contributions from unwanted cuts at the level of an expansion in the reciprocal omega=1/z variable. The modified sum over powers of omega produces the result from physical cuts only, with the nth coefficient precisely equal to the nth Mellin moment of the cross section. We demonstrate and validate our method for representative one- and two-loop diagrams.

   Glue Spin of the Proton

   Yi-Bo Yang🇺🇸 · Raza Sabbir Sufian🇺🇸 · Andrei Alexandru🇺🇸 · Terrence Draper🇺🇸 · Michael J. Glatzmaier🇺🇸 · Keh-Fei Liu🇺🇸

   We report the progress on the lattice QCD calculation of the glue spin contribution to proton spin. This calculation is carried out with valence overlap fermion on 2+1 flavor DWF gauge configurations at two lattice spacings with the momentum of the frame in the kinematic range $0\le p^2\le 2$ GeV${}^2$. A mild frame dependence is observed. The matching and mixing with large-momentum effective field theory are in progress. The unrenormalized result at $p^2=4$ GeV${}^2$ with $O(a^2)$ correction gives $S_G$ = 0.13(3).

   Probing Collective Effects in Hadronisation with the Extremes of the Underlying Event

   Tim Martin🇬🇧 · Peter Skands🇦🇺 · Sinead Farrington🇬🇧

   We define a new set of observables to probe the structure of the underlying event in hadron collisions. We use the conventional definition of the `transverse region' in jet events and, for a fixed window in jet $p_{\perp }$, propose to measure several discriminating quantities as a function of the level of activity in the transverse region. The measurement of these observables in LHC data would reveal whether, e.g., the properties of `low-UE' events are compatible with equivalent measurements in $e^{+}{e}^{-}$ collisions (jet universality), and whether the scaling behaviour towards `high-UE' events exhibits properties of non-trivial soft-QCD dynamics, such as colour re-connections or other collective phenomena. We illustrate at $\sqrt{s}=13$ TeV that significant discriminatory power is obtained in comparisons between MC models with varying treatments of collective effects, including Pythia 8, EPOS, and Dipsy.

   New physics and signal-background interference in associated $pp\to HZ$ production

   Christoph Englert🇬🇧 · Rogerio Rosenfeld🇧🇷 · Michael Spannowsky🇬🇧 · Alberto Tonero🇧🇷

   We re-investigate electroweak signal-background interference in associated Higgs production via gluon fusion in the presence of new physics in the top-Higgs sector. Considering the full final state $pp\to b\bar{b}{\ell }^{+}{\ell }^{-}$ ($\ell =e,\mu$), we discuss how new physics in the top-Higgs sector that enhances the $ZZ$ component can leave footprints in the $HZ$ limit setting. In passing we investigate the phenomenology of a class of new physics interactions that can be genuinely studied in this process.

   The ${\Lambda }_c(2595)$ resonance as a dynamically generated state: the compositeness condition and the large $N_c$ evolution

   Jun-Xu Lu🇨🇳 · Hua-Xing Chen🇨🇳 · Zhi-Hui Guo🇨🇳 · J. Nieves🇪🇸 · Ju-Jun Xie🇨🇳 · Li-Sheng Geng🇨🇳

   Recent studies have shown that the well established ${\Lambda }_c(2595)$ resonance contains a large meson-baryon component, which can vary depending on the specific formalism. In this work, we examine such a picture by utilizing the compositeness condition and the large number of colors ($N_c$) expansion. We examine three different models fulfilling two body unitarity in coupled-channels, and adopting renormalization schemes where the mass of the ${\Lambda }_c(2595)$ resonance is well described, but not necessarily its width, since we do not consider three body channels and work at the isospin symmetric limit. Both approximations might have an effect larger on the width than on the mass. In this context, our studies show that the compositeness of the ${\Lambda }_c(2595)$ depends on the number of considered coupled channels, and on the particular regularization scheme adopted in the unitary approaches and, therefore, is model dependent. In addition, we perform an exploratory study of the ${\Lambda }_c(2595)$ in the large $N_c$ expansion, within a scheme involving only the $\pi {\Sigma }_c$ and $K{\Xi }_c^{\prime }$ channels, whose dynamics is mostly fixed by chiral symmetry. In this context and formulating the leading-order interaction as a function of $N_c$, we show that for moderate $N_c>3$ values, the mass and width of the ${\Lambda }_c(2595)$ deviate from those of a genuine $qqq$ baryon, implying the relevance of meson-baryon components in its wave function. Furthermore, we study the properties of the ${\Lambda }_c(2595)$, in the strict $N_c\to \infty$ limit, using an extension of the chiral Weinberg-Tomozawa interaction to an arbitrary number of flavors and colors. This latter study hints at the possible existence of a (perhaps) sub-dominant $qqq$ component in the ${\Lambda }_c(2595)$ resonance wave function, which would become dominant when the number of colors gets sufficiently large.

    Z/gamma* plus Multiple Hard Jets in High Energy Collisions

    Jeppe R. Andersen🇬🇧 · Jack J. Medley🇬🇧 · Jennifer M. Smillie🇬🇧

    We present a description of the production of a di-lepton pair (through Z boson and virtual photon) in association with at least two jets. This calculation adds to the fixed-order accuracy the dominant logarithms in the limit of large partonic centre-of-mass energy to all orders in the strong coupling. This is achieved within the framework of High Energy Jets. This calculation is made possible by extending the high energy treatment to take into account the multiple t-channel exchanges arising from Z and gamma*-emissions off several quark lines. The correct description of the interference effects from the various t-channel exchanges requires an extension of the subtraction terms in the all-order calculation. We describe this construction and compare the resulting predictions to a number of recent analyses of LHC data. The description of a wide range of observables is good, and, as expected, stands out from other approaches in particular in the regions of large dijet invariant mass and large dijet rapidity spans.

    Double parton scattering in the ultraviolet: addressing the double counting problem

    Markus Diehl🇩🇪 · Jonathan R. Gaunt🇳🇱

    In proton-proton collisions there is a smooth transition between the regime of double parton scattering, initiated by two pairs of partons at a large relative distance, and the regime where a single parton splits into a parton pair in one or both protons. We present a scheme for computing both contributions in a consistent and practicable way.

    Revisiting the Exclusion Limits from Direct Chargino-Neutralino Production at the LHC

    Arghya Choudhury🇬🇧 · Subhadeep Mondal🇮🇳

    We revisit the existing limits on the gaugino masses in various Supersymmetric (SUSY) scenarios derived from Run-I data of the LHC. These limits obtained from the various final states rely heavily on the simplified assumptions regarding the masses, compositions and decay branching ratios of the gauginos. The most promising exclusion limits on the gaugino masses are obtained from trilepton final states while the second lightest neutralino (${\tilde{\chi }}_2^0$) decaying into the SM-like Higgs and lightest SUSY particle (LSP) results in the weakest bounds. Our aim is to assess the extent of deviation of these exclusion limits in more realistic scenarios. After a brief discussion on the various decay modes of the ${\tilde{\chi }}_2^0$ and the lightest chargino (${\tilde{\chi }}_1^{\pm }$), we proceed to validate the ATLAS exclusion limits obtained from trilepton, $l\gamma \gamma$ and $lb\bar{b}$ final states associated with missing energy. We then consider different combinations of the relevant branching ratios to study their impact on the existing bounds. The results are presented alongside the existing exclusion limits to showcase the extent of the obtained deviation. We also observe that the three-body decay modes of ${\tilde{\chi }}_2^0$ and ${\tilde{\chi }}_1^{\pm }$ via off-shell slepton decays resulting in trilepton final states provide bounds that are far more severe in some parts of the available parameter space than that obtained from the usual two-body decay modes of the aforementioned gauginos.

    The on-shell effective field theory: a systematic tool to compute power corrections to the hard thermal loops

    Cristina Manuel🇪🇸 · Joan Soto🇪🇸 · Stephan Stetina🇺🇸

    We show that effective field theory techniques can be efficiently used to compute power corrections to the hard thermal loops (HTL) in a high temperature T expansion. To this aim, we use the recently proposed on-shell effective field theory (OSEFT), which describes the quantum fluctuations around on-shell degrees of freedom. We provide the OSEFT Lagrangian up to third order in the energy expansion for QED, and use it for the computation of power corrections to the retarded photon polarization tensor for soft external momenta. Here soft denotes a scale of order $eT$, where $e$ is the gauge coupling constant. We develop the necessary techniques to perform these computations, and study the contributions to the polarization tensor proportional to $e^2{T}^2$, $e^{2}T$ and $e^2{T}^0$. The first one describes the HTL contribution, the second one vanishes, while the third one provides corrections of order $e^2$ to the soft photon propagation. We check that the results agree with the direct calculation from QED, up to local pieces, as expected in an effective field theory.

    Renormalisation of the low-energy constants of chiral perturbation theory from loops with dynamical vector mesons

    Carla Terschlüsen🇸🇪 · Stefan Leupold (Uppsala U.)🇸🇪

    Starting from a relativistic Lagrangian for pseudoscalar Goldstone bosons and vector mesons in the antisymmetric tensor representation, a one-loop calculation is performed to pin down the divergent structures that appear for the effective low-energy action at chiral orders Q^2 and Q^4. The corresponding renormalisation-scale dependences of all low-energy constants up to chiral order Q^4 are determined. Calculations are carried out for both the pseudoscalar octet and the pseudoscalar nonet, the latter in the framework of chiral perturbation theory in the limit of a large number of colours.

    General considerations on the nature of $Z_b(10610)$ and $Z_b(10650)$ from their pole positions

    Xian-Wei Kang🇪🇸 · Zhi-Hui Guo🇨🇳 · J. A. Oller🇪🇸

    The nature of the bottomonium-like states $Z_b(10610)$ and $Z_b(10650)$ is studied by calculating the $B^{(\ast )}{\overline{B}}^{\ast }$ compositeness ($X$) in those resonances. We first consider uncoupled isovector $S$-wave scattering of $B^{(\ast )}{\overline{B}}^{\ast }$ within the framework of effective-range expansion (ERE). Expressions for the scattering length ($a$) and effective range ($r$) are derived exclusively in terms of the masses and widths of the two $Z_b$ states. We then develop compositeness within ERE for the resonance case and deduce the expression $X=1/\sqrt{2r/a-1}$, which is then applied to the systems of interest. Finally, the actual compositeness parameters are calculated in terms of resonance pole positions and their experimental branching ratios into $B^{(\ast )}{\overline{B}}^{\ast }$ by using the method of Ref.[1]. We find the values $X=0.66\pm 0.11$ and $0.51\pm 0.10$ for the $Z_b(10610)$ and $Z_b(10650)$, respectively. We also compare the ERE with Breit-Wigner and Flatté parameterizations to discuss the applicability of the last two ones for near-threshold resonances with explicit examples.

    Theoretical interpretation of a spin-two diphoton excess

    Veronica Sanz🇬🇧

    A spin-two resonance would have couplings to the SM, suppressed via higher-dimensional operators. Therefore, a sizeable cross-section would indicate that the scale of additional new phenomena cannot be too far above the 750 GeV mark. Below I present some theoretical arguments to place the resonance in a wider framework: a manifestation of new extra-dimensions, or a glueball of a new strong sector. In each case, I identify some conditions the UV theory must satisfy to accommodate other experimental bounds. Based on those, I draw correlations with associated phenomena we expect to find in future searches.

    Single and double production of the Higgs boson at hadron and lepton colliders in minimal composite Higgs models

    Shinya Kanemura🇯🇵 · Kunio Kaneta🇰🇷 · Naoki Machida🇯🇵 · Shinya Odori🇯🇵 · Tetsuo Shindou🇯🇵

    In the composite Higgs models, originally proposed by Georgi and Kaplan, the Higgs boson is a pseudo Nambu-Goldstone boson (pNGB) of spontaneous breaking of a global symmetry. In the minimal version of such models, global SO(5) symmetry is spontaneously broken to SO(4), and the pNGBs form an isospin doublet field, which corresponds to the Higgs doublet in the Standard Model (SM). Predicted coupling constants of the Higgs boson can in general deviate from the SM predictions, depending on the compositeness parameter. The deviation pattern is determined also by the detail of the matter sector. We comprehensively study how the model can be tested via measuring single and double production processes of the Higgs boson at LHC and future electron-positron colliders. The possibility to distinguish the matter sector among the minimal composite Higgs models is also discussed. In addition, we point out differences in the cross section of double Higgs boson production from the prediction in other new physics models.

    The 750 GeV Diphoton excess, Dark Matter and Constraints from the IceCube experiment

    Enrico Morgante🇨🇭 · Davide Racco🇨🇭 · Mohamed Rameez🇨🇭 · Antonio Riotto🇨🇭

    Recent LHC data show hints of a new resonance in the diphoton distribution at an invariant mass of 750 GeV. Interestingly, this new particle might be both CP odd and play the role of a portal into the dark matter sector. Under these assumptions and motivated by the fact that the requirement of $SU(2{)}_L$ invariance automatically implies the coupling of this alleged new resonance to $ZZ$ and $Z\gamma$, we investigate the current and future constraints coming from the indirect searches performed through the neutrino telescope IceCube. We show that these constraints can be stronger than the ones from direct detection experiments if the dark matter mass is larger than a few hundred GeV. Furthermore, in the scenario in which the dark matter is a scalar particle, the IceCube data limit the cross section between the DM and the proton to values close to the predicted ones for natural values of the parameters.

    Elastic vector and axial scattering of weakly interacting particles off nuclei

    O. Moreno🇺🇸 · T. W. Donnelly🇺🇸

    We analyze the elastic scattering of particles interacting with nuclei through vector and axial currents with overall couplings of the order of the Standard Model weak interaction, or smaller; the dominant contribution to the elastic cross section is identified as the coherent component and is therefore spin-independent. Differential and integrated cross sections are obtained for a wide range of incident particle masses and velocities and for nuclear targets with different masses; vector, axial and overall couplings of the incident particle and of the hadronic target to the massive exchanged boson are also kept general. This study naturally encompasses several kinds of possible dark matter components, including active and sterile neutrinos or neutralinos, and addresses the prospects for their direct detection through elastic scattering off nuclei.

    Setting the Stage for a Non-Supersymmetric UV-Complete String Phenomenology

    Steven Abel🇬🇧 · Keith R. Dienes🇺🇸 · Eirini Mavroudi🇬🇧

    In this talk, I discuss our recent work concerning the construction of non-supersymmetric heterotic string models which have exponentially suppressed dilaton tadpoles and cosmological constants, and thus greatly enhanced stability properties. The existence of such models opens the door to non-supersymmetric string model-building, and I discuss how semi-realistic string models resembling the Standard Model or any of its unified variants may be constructed within this framework. These models maintain modular invariance and exhibit a misaligned supersymmetry which ensures UV finiteness, even without spacetime supersymmetry. I also discuss the potential implications for phenomenology.

    A Probabilistic Angle on One Loop Scalar Integrals

    Kamel Benhaddou

    Recasting the $N$-point one loop scalar integral as a probabilistic problem, allows the derivation of integral recurrence relations as well as exact analytical expressions in the most common cases. $ϵ$ expansions are derived by writing a formula that relates an $N$-point function in decimal dimension to an $N$-point function in integer dimension. As an example, we give relations for the massive 5-point function in dimension $n=4-2ϵ$, $n=6-2ϵ$. The reduction of tensor integrals of rank 2 with $N=5$ is achieved showing the method's potential. Hypergeometric functions are not needed but only integration of arcsine function whose analytical continuation is well known.

    Entropy Production, Hydrodynamics, and Resurgence in the Primordial Quark-Gluon Plasma from Holography

    Alex Buchel🇨🇦 · Michal P. Heller🇨🇦 · Jorge Noronha🇧🇷

    Microseconds after the Big Bang quarks and gluons formed a strongly-coupled non-conformal liquid driven out-of-equilibrium by the expansion of the Universe. We use holography to determine the non-equilibrium behavior of this liquid in a Friedmann-Lemaitre-Robertson-Walker Universe and develop an expansion for the corresponding entropy production in terms of the derivatives of the cosmological scale factor. We show that the resulting series has zero radius of convergence and we discuss its resurgent properties. Finally, we compute the resummed entropy production rate in de Sitter Universe at late times and show that the leading order approximation given by bulk viscosity effects can strongly overestimate/underestimate the rate depending on the microscopic parameters.

    Impact of sterile neutrino dark matter on core-collapse supernovae

    MacKenzie L. Warren🇺🇸 · Grant J. Mathews🇺🇸 · Matthew Meixner🇺🇸 · Jun Hidaka🇯🇵 · Toshitaka Kajino🇯🇵

    We summarize the impact of sterile neutrino dark matter on core-collapse supernova explosions. We explore various oscillations between electron neutrinos or mixed $\mu -\tau$ neutrinos and right-handed sterile neutrinos that may occur within a core-collapse supernova. In particular, we consider sterile neutrino masses and mixing angles that are consistent with sterile neutrino dark matter candidates as indicated by recent X-ray flux measurements. We find that the interpretation of the observed 3.5 keV X-ray excess as due to a decaying 7 keV sterile neutrino that comprises 100\% of the dark matter would have almost no observable effect on supernova explosions. However, in the more realistic case in which the decaying sterile neutrino comprises only a small fraction of the total dark matter density due to the presence of other sterile neutrino flavors, WIMPs, etc., a larger mixing angle is allowed. In this case a 7 keV sterile neutrino could have a significant impact on core-collapse supernovae. We also consider mixing between $\mu -\tau$ neutrinos and sterile neutrinos. We find, however, that this mixing does not significantly alter the explosion and has no observable effect on the neutrino luminosities at early times.

    Search for QCD Instanton-Induced Processes at HERA in the High-$Q^2$ Domain

    H1 Collaboration

    Signals of QCD instanton-induced processes are searched for in neutral current deep-inelastic scattering at the electron-proton collider HERA in the kinematic region defined by the Bjorken-scaling variable $x>10^{-3}$, the inelasticity $0.2<y<0.7$ and the photon virtuality $150<Q^2<15000$ GeV${}^2$. The search is performed using H1 data corresponding to an integrated luminosity of ~$351$ pb${}^{-1}$. No evidence for the production of QCD instanton-induced events is observed. Upper limits on the cross section for instanton-induced processes between $1.5$~pb and $6$~pb, at $95\%$~ confidence level, are obtained depending on the kinematic domain in which instantons could be produced. Compared to earlier publications, the limits are improved by an order of magnitude and for the first time are challenging theory predictions.

    Time-dependent Aharonov-Bohm effect on the noncommutative space

    Kai Ma🇨🇳 · Jian-Hua Wang🇨🇳 · Huan-Xiong Yang🇨🇳

    We study the time-dependent Aharonov-Bohm effect on the noncommutative space. Because there is no net Aharonov-Bohm phase shift in the time-dependent case on the commutative space, therefore, a tiny deviation from zero indicates new physics. Based on the Seiberg-Witten map we obtain the gauge invariant and Lorentz covariant Aharonov-Bohm phase shift in general case on noncommutative space. We find there are two kinds of contribution: momentum-dependent and momentum-independent corrections. For the momentum-dependent correction, there is a cancellation between the magnetic and electric phase shifts, just like the case on the commutative space. However, there is a non-trivial contribution in the momentum-independent correction. This is true for both the time-independent and time-dependent Aharonov-Bohm effects on the noncommutative space. However, for the time-dependent Aharonov-Bohm effect, there is no overwhelming background which exists in the time-independent Aharonov-Bohm effect on both commutative and noncommutative space. Therefore, the time-dependent Aharonov-Bohm can be sensitive to the spatial noncommutativity. \draftnote{The net correction is proportional to the product of the magnetic fluxes through the fundamental area represented by the noncommutative parameter $\theta$, and through the surface enclosed by the trajectory of charged particle.} More interestingly, there is an anti-collinear relation between the logarithms of the magnetic field $B$ and the averaged flux $\Phi /N$ (N is the number of fringes shifted). This nontrivial relation can also provide a way to test the spatial noncommutativity. For $B\Phi /N\sim 1$, our estimation on the experimental sensitivity shows that it can reach the $10GeV$ scale. This sensitivity can be enhanced by using stronger magnetic field strength, larger magnetic flux, as well as higher experimental precision on the phase shift.
