   Examining the time dependence of DAMA's modulation amplitude

   Chris Kelso🇺🇸 · Christopher Savage🇸🇪 · Pearl Sandick🇺🇸 · Katherine Freese🇸🇪 · Paolo Gondolo🇺🇸

   If dark matter is composed of weakly interacting particles, Earth's orbital motion may induce a small annual variation in the rate at which these particles interact in a terrestrial detector. The DAMA collaboration has identified at a 9.3$\sigma$ confidence level such an annual modulation in their event rate over two detector iterations, DAMA/NaI and DAMA/LIBRA, each with $\sim 7$ years of observations. We statistically examine the time dependence of the modulation amplitudes, which "by eye" appear to be decreasing with time in certain energy ranges. We perform a chi-squared goodness of fit test of the average modulation amplitudes measured\ by the two detector iterations which rejects the hypothesis of a consistent modulation amplitude at greater than 80\%, 96\%, and 99.6\% for the 2--4~keVee, 2--5~keVee and 2--6~keVee energy ranges, respectively. We also find that among the 14 annual cycles there are three $\gtrsim 3\sigma$ departures from the average in the 5-6~keVee energy range. In addition, we examined several phenomenological models for the time dependence of the modulation amplitude. Using a maximum likelihood test, we find that descriptions of the modulation amplitude as decreasing with time are preferred over a constant modulation amplitude at anywhere between 1$\sigma$ and 3$\sigma$, depending on the phenomenological model for the time dependence and the signal energy range considered. A time dependent modulation amplitude is not expected for a dark matter signal, at least for dark matter halo morphologies consistent with the DAMA signal. New data from DAMA/LIBRA--phase2 will certainly aid in determining whether any apparent time dependence is a real effect or a statistical fluctuation.

   The sounds of the Little and Big Bangs

   E.Shuryak🇺🇸

   Studies of heavy ion collisions have discovered that tiny fireballs of new phase of matter -- quark gluon plasma (QGP) -- undergoes explosion, called the Little Bang. In spite of its small size, it is not only well described by hydrodynamics, but even small perturbations on top of the explosion turned to be well described by hydrodynamical sound modes. The cosmological Big Bang also went through phase transitions, the QCD and electroweak ones, which are expected to produce sounds as well. We discuss their subsequent evolution and hypothetical inverse acoustic cascade, amplifying the amplitude. Ultimately, collision of two sound waves leads to formation of gravity waves, with the smallest wavelength. We briefly discuss how those can be detected.

   New Dark Matter Search Strategies at DUNE

   Carsten Rott🇰🇷 · Seongjin In🇰🇷 · Jason Kumar🇺🇸 · David Yaylali🇺🇸

   If dark matter annihilates to light quarks in the core of the Sun, then a flux of 236 MeV neutrinos will be produced from the decay of stopped kaons. We consider strategies for DUNE to not only observe such a signal, but to determine the direction of the neutrino from the hadronic recoil. We show that this novel strategy can provide a better handle on systematic uncertainties associated with dark matter searches.

   Radiative Neutrino Mass & Majorana Dark Matter within an Inert Higgs Doublet Model

   Amine Ahriche (1 and 2)🇩🇿 · Adil Jueid (3 and 4)🇨🇳 · Salah Nasri (5 and 6) ((1) Jijel U., (2) ICTP, Trieste, (3) Abdelmalek Essaadi U., (4) Shanghai Jiao Tong U., (5) United Arab Emirates U.)🇦🇪

   We consider an extension of the standard model (SM) with an inert Higgs doublet and three Majorana singlet fermions to address both origin and the smallness of neutrino masses and dark matter (DM) problems. In this setup, the lightest Majorana singlet fermion plays the role of DM candidate and the model parameter space can be accommodated to avoid different experimental constraints such as lepton flavor violating processes and electroweak precision tests. The neutrino mass is generated at one-loop level a la Scotogenic model and its smallness is ensured by the degeneracy between the CP-odd and CP-even scalar members of the inert doublet. Interesting signatures at both leptonic and hadronic colliders are discussed.

   Exploratory study of possible resonances in the heavy meson - heavy baryon coupled-channel interactions

   Chao-Wei Shen🇨🇳 · Deborah Rönchen🇩🇪 · Ulf-G. Meißner🇩🇪 · Bing-Song Zou🇨🇳

   We use a unitary coupled-channel model to study the $\bar{D}{\Lambda }_c-\bar{D}{\Sigma }_c$ interactions. In our calculation, SU(3) flavor symmetry is applied to determine the coupling constants. Several resonant and bound states with different spin and parity are dynamically generated in the mass range of the recently observed pentaquarks. The approach is also extended to the hidden beauty sector to study the $B{\Lambda }_b-B{\Sigma }_b$ interactions. As the $b$-quark mass is heavier than the $c$-quark mass, there are more resonances observed for $B{\Lambda }_b-B{\Sigma }_b$ interactions and they are more tightly bound.

   Four-body decays of $B$ meson with lepton number violation

   Han Yuan🇨🇳 · Tianhong Wang🇨🇳 · Yue Jiang🇨🇳 · Qiang Li🇨🇳 · Guo-Li Wang🇨🇳

   This paper is designed to calculate the branching ratio of four-body decays of $B$ meson with lepton number changed by 2. With the new experimental data limit to lepton-number violation processes, we update the upper limits of mixing parameters between heavy Majorana neutrino and charged leptons. Afterwards, we calculate the branching ratio of $B^0(P)\to D^{\ast -}(P_1){\ell }_1^{+}(P_2){\ell }_2^{+}(P_3)M_2^{-}(P_4)$ using the updated parameters. It is found that the most hopeful decay channel is $B^0(P)\to D^{\ast -}(P_1)e_1^{+}(P_2)e_2^{+}(P_3){\rho }^{-}(P_4)$ or $B^0(P)\to D^{\ast -}(P_1)e(\mu {)}_1^{+}(P_2)\mu (e{)}_2^{+}(P_3){\rho }^{-}(P_4)$, whose branching ratio can reach about $10^{-4}$ with heavy Majorana neutrino mass range around $2\mathrm{GeV}$.

   Explanation of the 511 keV line: Cascade annihilating dark matter with the ${}^8$Be anomaly

   Lian-Bao Jia🇨🇳

   A possible dark matter (DM) explanation about the long-standing issue of the Galactic 511 keV line is explored in this paper. For DM cascade annihilations of concern, a DM pair ${\pi }_d^{+}{\pi }_d^{-}$ annihilates into unstable ${\pi }_d^0{\pi }_d^0$, and ${\pi }_d^0$ decays into $e^{+}{e}^{-}$ with new interactions suggested by the ${}^8$Be anomaly. Considering the constraints from the effective neutrino number $N_{\mathrm{eff}}$ and the 511 keV gamma-ray emission, a range of DM is obtained, $11.6\lesssim m_{{\pi }_d^{\pm }}\lesssim 15$ MeV. The typical DM annihilation cross section today is about 3.3 $\times$ $10^{-29}$ cm${}^3$ s${}^{-1}$, which can give an explanation about the 511 keV line. The MeV scale DM may be searched by the DM-electron scattering, and the upper limit set by the CMB s-wave annihilation is derived in DM direct detections.

   Strong decays of $D_J(3000)$ and $D_{sJ}(3040)$

   Si-Chen Li🇨🇳 · Tianhong Wang🇨🇳 · Yue Jiang🇨🇳 · Xiao-Ze Tan🇨🇳 · Qiang Li🇨🇳 · Guo-Li Wang🇨🇳 · Chao-Hsi Chang🇨🇳

   In this paper, we systematically calculate two-body strong decays of newly observed $D_J(3000)$ and $D_{sJ}(3040)$ with 2P$(1^{+})$ and 2P$(1^{+\prime })$ assignments in an instantaneous approximation of the Bethe-Salpeter equation method. Our results show that both resonances can be explained as the 2P$(1^{{+}^{\prime }})$ with broad width via ${}^3{P}_1$ and ${}^1{P}_1$ mixing in $D$ and $D_s$ families. For $D_J(3000)$, the total width is 229.6 MeV in our calculation, close to the upper limit of experimental data, and the dominant decay channels are $D_2^{\ast }\pi$, $D^{\ast }\pi$, and $D^{\ast }(2600)\pi$. For $D_{sJ}(3040)$, the total width is 157.4 MeV in our calculation, close to the lower limit of experimental data, and the dominant channels are $D^{\ast }K$ and $D^{\ast }{K}^{\ast }$. These results are consistent with observed channels in experiments. Given the very little information that has been obtained from experiments and the large error bars of the total decay widths, we recommend the detection of dominant channels in our calculation.

   Probing Dark Matter Long-lived Mediators with Solar $\gamma$ rays

   Michele Lucente🇧🇪 · Chiara Arina🇧🇪 · Mihailo Backović🇧🇪 · Jan Heisig🇩🇪

   We show that solar $\gamma$-ray observations can provide a complementary probe of Dark Matter in scenarios where the interactions with the Standard Model proceed via long-lived mediators. For illustration we consider a simplified model which provides solar $\gamma$-ray fluxes observable with the next generation $\gamma$-ray telescopes, while complying with the existing experimental constraints. Our results suggest that solar $\gamma$-ray fluxes can be orders of magnitude larger than the ones from the Galactic center, while being subject to low backgrounds.

    The role of the triangle singularity in $\Lambda (1405)$ production in the ${\pi }^{-}p\to K^0\pi \Sigma$ and $pp\to p{K}^{+}\pi \Sigma$ processes

    M. Bayar🇹🇷 · R. Pavao🇪🇸 · S. Sakai🇪🇸 · E. Oset🇪🇸

    We have investigated the cross section for the ${\pi }^{-}p\to K^0\pi \Sigma$ and $pp\to p{K}^{+}\pi \Sigma$ reactions paying attention to a mechanism that develops a triangle singularity. The triangle diagram is realized by the decay of a $N^{\ast }$ to $K^{\ast }\Sigma$ and the $K^{\ast }$ decay into $\pi K$, and the $\pi \Sigma$ finally merges into $\Lambda (1405)$. The mechanism is expected to produce a peak around $2140$ MeV in the $K\Lambda (1405)$ invariant mass. We found that a clear peak appears around $2100$ MeV in the $K\Lambda (1405)$ invariant mass which is about $40$ MeV lower than the expectation, and that is due to the resonance peak of a $N^{\ast }$ resonance which plays a crucial role in the $K^{\ast }\Sigma$ production. The mechanism studied produces the peak of the $\Lambda (1405)$ around or below 1400 MeV, as is seen in the $pp\to p{K}^{+}\pi \Sigma$ HADES experiment.

    Electroweak Baryogenesis and the Standard Model Effective Field Theory

    Jordy de Vries🇳🇱 · Marieke Postma🇳🇱 · Jorinde van de Vis🇳🇱 · Graham White🇨🇦

    We investigate electroweak baryogenesis within the framework of the Standard Model Effective Field Theory. The Standard Model Lagrangian is supplemented by dimension-six operators that facilitate a strong first-order electroweak phase transition and provide sufficient CP violation. Two explicit scenarios are studied that are related via the classical equations of motion and are therefore identical at leading order in the effective field theory expansion. We demonstrate that formally higher-order dimension-eight corrections lead to large modifications of the matter-antimatter asymmetry. The effective field theory expansion breaks down in the modified Higgs sector due to the requirement of a first-order phase transition. We investigate the source of the breakdown in detail and show how it is transferred to the CP-violating sector. We briefly discuss possible modifications of the effective field theory framework.

    Collinear and Transverse Momentum Dependent parton densities obtained with a Parton Branching Method

    Aleksandra Lelek (DESY)🇩🇪

    We present a solution of the DGLAP evolution equations, written in terms of Sudakov form factors to describe the branching and no-branching probabilities, using a parton branching Monte Carlo method. We demonstrate numerically that this method reproduces the semi-analytical solutions. We show how this method can be used to determine Transverse Momentum Dependent (TMD) parton distribution functions, in addition to the usual integrated parton distributions functions. We discuss numerical effects of the boundary of soft gluon resolution scale parameter on the resulting parton distribution functions. We show that a very good fit of the integrated TMDs to high precision HERA data can be obtained over a large range in x and Q^2.

    New physics solutions for $R_D$ and $R_{D^{\ast }}$

    Ashutosh Kumar Alok🇮🇳 · Dinesh Kumar🇮🇳 · Jacky Kumar🇮🇳 · Suman Kumbhakar🇮🇳 · S Uma Sankar🇮🇳

    Recent measurements of $R_{D^{\ast }}$ have reduced tension with the Standard Model prediction. Taking all the present data into account, we obtain the values of the Wilson coefficients of each new physics four-fermion operator of a given Lorentz structure. We find that the combined data rule out most of the solutions based on scalar/pseudoscalar operators. By studying the inter-relations between different solutions, we find that there are only four allowed solutions, which are based on operators with $(V-A)$, linear combination of $(V-A)$ and $(V+A)$, tensor and linear combination of scalar/pseudoscalar and tensor structure. We demonstrate that the need for new physics is driven by those measurement of $R_D$ and $R_{D^{\ast }}$ where the $\tau$ lepton is not studied. Further, we show that new physics only in $b\to c\mu \bar{\nu }$ is not compatible with the full set of observables in the decays $B\to Dl\bar{\nu }$ and $B\to D^{\ast }l\bar{\nu }$.

    Electroweak Higgs production with HiggsPO at NLO QCD

    Admir Greljo🇨🇭 · Gino Isidori🇨🇭 · Jonas M. Lindert🇬🇧 · David Marzocca🇮🇹 · Hantian Zhang🇨🇭

    We present the HiggsPO UFO model for Monte Carlo event generation of electroweak $VH$ and VBF Higgs production processes at NLO in QCD in the formalism of Higgs pseudo-observables (PO). We illustrate the use of this tool by studying the QCD corrections, matched to a parton shower, for several benchmark points in the Higgs PO parameter space. We find that, while being sizable and thus important to be considered in realistic experimental analyses, the QCD higher-order corrections largely factorize. As an additional finding, based on the NLO results, we advocate to consider 2D distributions of the two-jet azimuthal-angle difference and the leading jet $p_T$ for new physics searches in VBF Higgs production. The HiggsPO UFO model is publicly available.

    NNLO QCD corrections to production of a spin-2 particle with non-universal couplings in the DY process

    Pulak Banerjee🇮🇳 · Prasanna K. Dhani🇮🇳 · M.C. Kumar🇮🇳 · Prakash Mathews🇮🇳 · V. Ravindran🇮🇳

    We study the phenomenological impact of the interaction of spin-2 fields with those of the Standard Model in a model independent framework up to next-to-next-to-leading order in perturbative Quantum Chromodynamics. We use the invariant mass distribution of the pair of leptons produced at the LHC to demonstrate this. A minimal scenario where the spin-2 fields couple to two gauge invariant operators with different coupling strengths has been considered. These operators being not conserved show very different ultraviolet behaviour increasing the searches options of spin-2 particles at the colliders. We find that our results using the higher order quantum corrections stabilise the predictions with respect to renormalisation and factorisation scales. We also find that corrections are appreciable which need to be taken into account in such searches at the colliders.

    Factoring the Strong CP Problem

    Prateek Agrawal🇺🇸 · Kiel Howe🇺🇸

    We present a new mechanism to solve the strong CP problem using $N\ge 2$ axions, each dynamically relaxing part of the $\bar{\theta }$ parameter. At high energies $M\gg {\Lambda }_{QCD}$ the $SU(3{)}_c$ group becomes the diagonal subgroup of an $SU(3{)}^N$ gauge group, and the non-perturbative effects in each individual $SU(3)$ factor generate a potential for the corresponding axion. The vacuum is naturally aligned to ensure $\bar{\theta }=0$ at low energies, and the masses of these axions can be much larger than for the standard QCD axion. This mechanism avoids the introduction of a discrete $Z_2$ symmetry and associated 'mirror' copies of the SM fermions, and also avoids the introduction and stabilization of new light colored states to modify the running of the QCD gauge coupling found in other heavy axion models. This strengthens the motivation for axion-like particles solving the strong CP problem at points beyond the standard QCD axion curve in the $(m_a,f_a)$ plane.

    Global Anomalies, Discrete Symmetries, and Hydrodynamic Effective Actions

    Paolo Glorioso🇺🇸 · Hong Liu🇺🇸 · Srivatsan Rajagopal🇺🇸

    We derive effective actions for parity-violating fluids in both $(3+1)$ and $(2+1)$ dimensions, including those with anomalies. As a corollary we confirm the most general constitutive relations for such systems derived previously using other methods. We discuss in detail connections between parity-odd transport and underlying discrete symmetries. In (3+1) dimensions we elucidate connections between anomalous transport coefficients and global anomalies, and clarify a previous puzzle concerning transports and local gravitational anomalies.

    Renormalizable, asymptotically free gravity without ghosts or tachyons

    Martin B. Einhorn🇺🇸 · D. R. Timothy Jones🇺🇸

    We analyse scale invariant quadratic quantum gravity incorporating non-minimal coupling to a multiplet of scalar fields in a gauge theory, with particular emphasis on the consequences for its interpretation resulting from a transformation from the Jordan frame to the Einstein frame. The result is the natural emergence of a de Sitter space solution which, depending the gauge theory and region of parameter space chosen, can be free of ghosts and tachyons, and completely asymptotically free. In the case of an SO(10) model, we present a detailed account of the spontaneous symmetry breaking, and we calculate the leading (two-loop) contribution to the dilaton mass.

    Plasmon mass scale and quantum fluctuations of classical fields on a real time lattice

    Tuomas Lappi🇫🇮 · Aleksi Kurkela🇨🇭 · Jarkko Peuron🇫🇮

    Classical real-time lattice simulations play an important role in understanding non-equilibrium phenomena in gauge theories and are used in particular to model the prethermal evolution of heavy-ion collisions. Above the Debye scale the classical Yang-Mills (CYM) theory can be matched smoothly to kinetic theory. First we study the limits of the quasiparticle picture of the CYM fields by determining the plasmon mass of the system using 3 different methods. Then we argue that one needs a numerical calculation of a system of classical gauge fields and small linearized fluctuations which correspond to quantum fluctuations, in a way that keeps the separation between the two manifest. We demonstrate and test an implementation of an algorithm with the linearized fluctuations showing that the linearization indeed works and the Gauss's law is conserved.

    The Adler $D$-function for $\mathcal{N}=1$ SQCD regularized by higher covariant derivatives in the three-loop approximation

    A.L.Kataev🇷🇺 · A.E.Kazantsev🇷🇺 · K.V.Stepanyantz🇷🇺

    We calculate the Adler $D$-function for $\mathcal{N}=1$ SQCD in the three-loop approximation using the higher covariant derivative regularization and the NSVZ-like subtraction scheme. The recently formulated all-order relation between the Adler function and the anomalous dimension of the matter superfields defined in terms of the bare coupling constant is first considered and generalized to the case of an arbitrary representation for the chiral matter superfields. The correctness of this all-order relation is explicitly verified at the three-loop level. The special renormalization scheme in which this all-order relation remains valid for the $D$-function and the anomalous dimension defined in terms of the renormalized coupling constant is constructed in the case of using the higher derivative regularization. The analytic expression for the Adler function for $\mathcal{N}=1$ SQCD is found in this scheme to the order $O({\alpha }_s^2)$. The problem of scheme-dependence of the $D$-function and the NSVZ-like equation is briefly discussed.

    Ultra-High Energy Neutrino Afterglows of nearby Long Duration Gamma-Ray Bursts

    Jessymol K. Thomas🇿🇦 · Reetanjali Moharana🇿🇦 · Soebur Razzaque🇿🇦

    Detection of ultra-high energy (UHE, $\gtrsim 1$ PeV) neutrinos from astrophysical sources will be a major advancement in identifying and understanding the sources of UHE cosmic rays (CRs) in nature. Long duration gamma-ray burst (GRB) blast waves have been considered as potential acceleration sites of UHECRs. These CRs are expected to interact with GRB afterglow photons, which is synchrotron radiation from relativistic electrons co-accelerated with CRs in the blast wave, and naturally produce UHE neutrinos. Fluxes of these neutrinos are uncertain, however, and crucially depend on the observed afterglow modeling. We have selected a sample of 23 long duration GRBs within redshift 0.5 for which adequate electromagnetic afterglow data are available and which could produce high flux of UHE afterglow neutrinos, being nearby. We fit optical, X-ray and $\gamma$-ray afterglow data with an adiabatic blast wave model in a constant density interstellar medium and in a wind environment where the density of the wind decreases as inverse square of the radius from the center of the GRB. The blast wave model parameters extracted from these fits are then used for calculating UHECR acceleration and $p\gamma$ interactions to produce UHE neutrino fluxes from these GRBs. We have also explored the detectability of these neutrinos by currently running and upcoming large area neutrino detectors, such as the Pierre Auger Observatory, IceCube Gen-2 and KM3NeT observatories. We find that our realistic flux models from nearby GRBs will be unconstrained in foreseeable future.

    Working Group 5: Physics with Heavy Flavours

    Andrea Giammanco🇧🇪 · Rhorry Gauld🇨🇭 · Alex Pearce🇨🇭

    This paper summarises a few selected topics discussed during Working Group 5 of the Deep Inelastic Scattering 2017 conference, Physics with Heavy Flavours, related to the study of charm, bottom, and top quark physics. While the programme of this Working Group was structured by thematic areas, this conference was the occasion for intense cross-pollination between traditionally disjoint research lines. The four LHC experiments all contribute to heavy-flavour physics, with some degree of overlap in most areas, while experiments at other accelerators provide vital input in complimentary kinematic regions. Theorists now have the possibility to take inputs from more sources, and experimentalists focus on measurements that maximise utility. The interplay of LHC heavy quark cross-section measurements with DIS expertise is greatly improving PDF precision, leading to much improved models that, amongst other things, better inform the prospects for future colliders.

    The Clockwork Supergravity

    Alex Kehagias🇬🇷 · Antonio Riotto🇨🇭

    We show that the minimal D = 5, N = 2 gauged supergravity set-up may encode naturally the recently proposed clockwork mechanism. The minimal embedding requires one vector multiplet in addition to the supergravity multiplet and the clockwork scalar is identified with the scalar in the vector multiplet. The scalar has a two-parameter potential and it can accommodate the clockwork, the Randall-Sundrum and a no-scale model with a flat potential, depending on the values of the parameters. The continuous clockwork background breaks half of the original supersymmetries, leaving a D = 4, N = 1 theory on the boundaries. We also show that the generated hierarchy by the clockwork is not exponential but rather power law. The reason is that four-dimensional Planck scale has a power-law dependence on the compactification radius, whereas the corresponding KK spectrum depends on the logarithm of the latter.

    The Wilsonian renormalization group approach to the Lippmann-Schwinger equation with a multitude of cutoff parameters is introduced. A system of integro-differential equations for the cutoff-dependent potential is obtained. As an illustration, a perturbative solution of these equations with two cutoff parameters for a simple case of an S-wave low-energy potential in the form of a Taylor series in momenta is obtained. The relevance of the obtained results for the effective field theory approach to nucleon-nucleon scattering is discussed.
