   Gauge mediation with light stops

   Antonio Delgado🇺🇸 · Mateo Garcia-Pepin🇪🇸 · Mariano Quiros🇪🇸

   The mechanism of gauge mediated supersymmetry breaking (GMSB) solves the supersymmetric flavor problem although it requires superheavy stops to reproduce the experimental value (125 GeV) of the Higgs mass. A possible way out is to extend the MSSM Higgs sector with triplets which provide extra tree-level corrections to the Higgs mass. Triplets with neutral components getting vacuum expectation values (VEV) have the problem of generating a tree-level correction to the \rho parameter. We introduce supersymmetric triplets with hypercharges Y=(0,\pm 1), with a tree-level custodial SU(2)_L\otimes SU(2)_R global symmetry in the Higgs sector protecting the \rho parameter: a supersymmetric generalization of the Georgi-Machacek model. The renormalization group running from the messenger to the electroweak scale mildly breaks the custodial symmetry. We will present realistic low-scale scenarios, their main features being a Bino-like neutralino or right-handed stau as the NLSP, light (1 TeV) stops, exotic couplings (H^\pm W^\mp Z and H^{\pm\pm} W^\mp W^\mp) absent in the MSSM and proportional to the triplet VEV, and a possible (measurable) universality breaking of the Higgs couplings \lambda_{WZ}= \left(g_{hWW}/g_{hWW}^{SM}\right)/ \left(g_{hZZ}/g_{hZZ}^{SM}\right)\neq 1.

   Electric Dipole Moments of Charged Leptons with Sterile Fermions

   Asmaa Abada🇫🇷 · Takashi Toma🇫🇷

   We address the impact of sterile fermions on charged lepton electric dipole moments. Any experimental signal of these observables calls for scenarios of physics beyond the Standard Model providing new sources of CP violation. In this work, we consider a minimal extension of the Standard Model via the addition of sterile fermions which mix with active neutrinos and we derive the corresponding analytical expressions for the electric dipole moments of charged leptons at two-loop order. Our study reveals that, in order to have a non-vanishing contribution in this framework, the minimal extension necessitates the addition of at least 2 sterile fermion states to the Standard Model field content. Our conclusion is that sterile neutrinos can give significant contributions to the charged lepton electric dipole moments, some of them lying within present and future experimental sensitivity if the masses of the non-degenerate sterile states are both above the electroweak scale. The Majorana nature of neutrinos is also important in order to allow for significative contributions to the charged lepton electric dipole moments. In our analysis we impose all available experimental and observational constraints on sterile neutrinos and we further discuss the prospect of probing this scenario at low and high energy experiments.

   Planckian Interacting Massive Particles as Dark Matter

   Mathias Garny🇨🇭 · McCullen Sandora🇩🇰 · Martin S. Sloth🇩🇰

   The Standard Model could be self-consistent up to the Planck scale according to the present measurements of the Higgs mass and top quark Yukawa coupling. It is therefore possible that new physics is only coupled to the Standard Model through Planck suppressed higher dimensional operators. In this case the WIMP miracle is a mirage, and instead minimality as dictated by Occam's razor would indicate that dark matter is related to the Planck scale, where quantum gravity is anyway expected to manifest itself. Assuming within this framework that dark matter is a Planckian Interacting Massive Particle, we show that the most natural mass larger than $0.01{\text{M}}_p$ is already ruled out by the absence of tensor modes in the CMB. This also indicates that we expect tensor modes in the CMB to be observed soon for this type of minimal dark matter model. Finally, we touch upon the KK graviton mode as a possible realization of this scenario within UV complete models, as well as further potential signatures and peculiar properties of this type of dark matter candidate. This paradigm therefore leads to a subtle connection between quantum gravity, the physics of primordial inflation, and the nature of dark matter.

   $\bar{B}\to D^{(\ast )}\tau \bar{\nu }$ excesses in ALRSM constrained from $B$, $D$ decays and $D^0-{\bar{D}}^0$ mixing

   Chandan Hati🇮🇳 · Girish Kumar🇮🇳 · Namit Mahajan🇮🇳

   Recent experimental results from the LHCb, BaBar and Belle collaborations on the semitauonic decays of $B$ meson, $\bar{B}\to D^{(\ast )}\tau \bar{\nu }$, showing a significant deviation from the Standard Model (SM), hint towards a new physics scenario beyond the SM. In this work, we show that these enhanced decay rates can be explained within the framework of $E_6$ motivated Alternative Left-Right Symmetric Model (ALRSM), which has been successful in explaining the recent CMS excesses and has the feature of accommodating high scale leptogenesis. The R-parity conserving couplings in ALRSM can contribute universally to both $\bar{B}\to D\tau \bar{\nu }$ and $\bar{B}\to D^{(\ast )}\tau \bar{\nu }$ via the exchange of scalar leptoquarks. We study the leptonic decays $D_s^{+}\to {\tau }^{+}\bar{\nu }$, $B^{+}\to {\tau }^{+}\bar{\nu }$, $D^{+}\to {\tau }^{+}\bar{\nu }$ and $D^0$-${\bar{D}}^0$ mixing to constrain the couplings involved in explaining the enhanced $B$ decay rates and we find that ALRSM can explain the current experimental data on $\mathcal{R}(D^{(\ast )})$ quite well while satisfying these constraints.

   Modified nonlinear model of arcsin-electrodynamics

   S.I. Kruglov🇨🇦

   A new modified model of nonlinear arcsin-electrodynamics with two parameters is proposed and analyzed. We obtain the corrections to the Coulomb law. The effect of vacuum birefringence takes place when the external constant magnetic field is present. We calculate indices of refraction for two perpendicular polarizations of electromagnetic waves and estimate bounds on the parameter $\gamma$ from the BMV and PVLAS experiments. It is shown that the electric field of a point-like charge is finite at the origin. We calculate the finite static electric energy of point-like particles and demonstrate that the electron mass can have the pure electromagnetic nature. The symmetrical Belinfante energy-momentum tensor and dilatation current are found. We show that the dilatation symmetry and dual symmetry are broken in the model suggested. We have investigated the gauge covariant quantization of the nonlinear electrodynamics fields as well as the gauge fixing approach based on Dirac's brackets.

   Measuring Trilinear Higgs Coupling in $WHH$ and $ZHH$ Productions at the HL-LHC

   Qing-Hong Cao🇨🇳 · Yandong Liu🇨🇳 · Bin Yan🇨🇳

   Determination of trilinear Higgs coupling (${\lambda }_{HHH}=\kappa {\lambda }_{HHH}^{\mathrm{SM}}$) through Higgs pair productions is a major motivation for the LHC high luminosity phase. We perform a detailed collider simulation to explore the potential of measuring ${\lambda }_{HHH}$ in the $VHH$ ($V=W,Z$) production at the HL-LHC. We find that the trilinear Higgs coupling in the SM (${\lambda }_{HHH}^{\mathrm{SM}}$) could be measured at the level of $1.3\sigma$. Combining with the gluon fusion, vector boson fusion and $t\bar{t}HH$ channels, ${\lambda }_{HHH}^{\mathrm{SM}}$ is expected to be measured at the level of $3.13\sigma$. If no evidence of Higgs pair productions were observed, the $VHH$ production, together with the gluon fusion channel, would impose a bound of $0.5\le \kappa \le 2.2$ at the 95\% confidence level.

   Constant matter neutrino oscillations in a parametrization-free formulation

   L. J. Flores🇲🇽 · O. G. Miranda🇲🇽

   Neutrino oscillations are now a well-stablished and deeply studied phenomena. Their mixing parameters, except for the CP phase, are measured with good accuracy. The three-neutrino oscillation picture in matter is currently of great interest due to the different long-baseline neutrino experiments that are already running or under construction. In this work, we reanalyze the exact expression for the neutrino probabilities (in a constant density medium) and introduce an approximate formula. Our results are shown in a formulation that is independent of the parametrization and could be useful for unitary tests of the leptonic mixing matrix. We illustrate how the approximation, besides being simple, can reproduce the neutrino probabilities with good accuracy.

   Study of the $\psi (1S,2S)$ and ${\eta }_c(1S,2S)$ weak decays into $DM$

   Junfeng Sun🇨🇳 · Yueling Yang🇨🇳 · Jinshu Huang🇨🇳 · Lili Chen🇨🇳 · Qin Chang🇨🇳

   Inspired by the recent measurements on the $J/\psi (1S)$ $\to$ $D_s\rho$, $D_u{K}^{\ast }$ weak decays at BESIII and the potential prospects of the charmonium at the high-luminosity heavy-flavor experiments, we study $\psi (1S,2S)$ and ${\eta }_c(1S,2S)$ weak decays into final states including one charmed meson plus one light meson, considering the QCD corrections to hadronic matrix elements with the QCD factorization. It is found that the Cabibbo favored $\psi (1S,2S)$ $\to$ $D_s^{-}{\rho }^{+}$, $D_s^{-}{\pi }^{+}$, ${\overline{D}}_u^0{\overline{K}}^{\ast 0}$ decays have branching ratios $\gtrsim$ $10^{-10}$, which might be accessible at the future experiments.

   Non-custodial warped extra dimensions at the LHC

   Barry M. Dillon🇬🇧 · Stephan J. Huber🇬🇧

   With the prospect of improved Higgs measurements at the LHC and at proposed future colliders such as ILC, CLIC and TLEP we study the non-custodial Randall-Sundrum model with bulk SM fields and compare brane and bulk Higgs scenarios. We compute the electroweak precision observables and argue that incalculable contributions to these, in the form of higher dimensional operators, could have a non-negligable impact. This could potentially reduce the bound on the lowest Kaluza-Klein gauge boson masses to the 5 TeV range, making these states detectable at the LHC. In a second part, we compute the misalignment between fermion masses and Yukawa couplings caused by vector-like Kaluza-Klein fermions. The deviation of the top Yukawa can easily reach 10%, making it observable at the high-luminosity LHC. Corrections to the bottom and tau Yukawa couplings can be at the percent level and detectable at ILC, CLIC or TLEP.

    Full analysis of general non-standard tbW couplings

    Zenro Hioki (U. Tokushima)🇯🇵 · Kazumasa Ohkuma (Okayama U. Science)🇯🇵

    Possible non-standard couplings which could contribute to the t -> b W process are studied based on the effective-Lagrangian approach. The corresponding effective Lagrangian consists of four kinds of dimension-6 effective operators, each of which has an independent coupling constant. In this analysis, all those couplings are treated as complex numbers and constraints on them are estimated by using recent experimental data from the LHC. We point out that the resultant constraints on those couplings are still not that strong because contributions from some couplings can work oppositely with each other.

    Predictions of the hidden-charm molecular states with four-quark component

    Rui Chen🇨🇳 · Xiang Liu🇨🇳 · Yan-Rui Liu🇨🇳 · Shi-Lin Zhu🇨🇳

    In this work, we study the $T\bar{T}$-type molecular systems systematically via one pion exchange model, where $T$ denotes the narrow $J^P=1^{+}$ $D_1$ meson or $2^{+}$ $D_2^{\ast }$ meson and $\bar{T}$ is its antiparticle. With the effective potentials, we try to find the bound state solutions of the corresponding systems, which provide crucial information of whether there exist the $T\bar{T}$-type molecular states. According to our analysis, we predict some $T\bar{T}$-type molecular states which may be accessible at future experiments like LHCb and forthcoming BelleII.

    Some Aspects of Three-Quark Potentials

    Oleg Andreev🇷🇺

    We analytically evaluate the expectation value of a baryonic Wilson loop in a holographic model of an SU(3) pure gauge theory. We then discuss three aspects of a static three-quark potential: an aspect of universality which concerns properties independent of a geometric configuration of quarks; a heavy diquark structure; and a relation between the three and two-quark potentials.

    Single spin asymmetries from a single Wilson loop

    Daniël Boer🇳🇱 · Miguel G. Echevarria🇳🇱 · Piet Mulders🇳🇱 · Jian Zhou🇨🇳

    We study the leading-power gluon transverse momentum dependent distributions (TMDs) of relevance to the study of asymmetries in the scattering off transversely polarized hadrons. Next-to-leading-order perturbative calculations of these TMDs show that at large transverse momentum they have common dynamical origins, but that in the limit of small longitudinal momentum fraction $x$ only one origin remains. We find that in this limit only the dipole-type gluon TMDs survive and become identical to each other. At small $x$ they are all given by the expectation value of a single Wilson loop inside the transversely polarized hadron, the so-called spin-dependent odderon. This universal origin of transverse spin asymmetries at small $x$ is of importance to current and future experimental studies, paving the way to a better understanding of the role of gluons in the three-dimensional structure of spin-polarized protons.

    Data-driven estimation of neutral pileup particle multiplicity in high-luminosity hadron collider environments

    Federico Colecchia🇬🇧

    The upcoming operation regimes of the Large Hadron Collider are going to place stronger requirements on the rejection of particles originating from pileup, i.e. from interactions between other protons. For this reason, particle weighting techniques have recently been proposed in order to subtract pileup at the level of individual particles. We describe a choice of weights that, unlike others that rely on particle proximity, exploits the particle-level kinematic signatures of the high-energy scattering and of the pileup interactions. We illustrate the use of the weights to estimate the number density of neutral pileup particles inside individual events, and we elaborate on the complementarity between ours and other methods. We conclude by suggesting the idea of combining different sets of weights with a view to exploiting different features of the underlying processes for improved pileup subtraction at higher luminosity.

    Annihilation type rare radiative $B_{(s)}\to V\gamma$ decays

    Anastasiya Kozachuk🇷🇺 · Dmitri Melikhov🇷🇺 · Nikolai Nikitin🇷🇺

    We obtain predictions for a number of radiative decays $B_{(s)}\to V\gamma$, $V$ the vector meson, which proceed through the weak-annihilation mechanism. Within the factorization approximation, we take into account the photon emission from the $B$-meson loop and from the vector-meson loop; the latter subprocesses were not considered in the previous analyses but are found to have sizeable impact on the $B_{(s)}\to V\gamma$ decay rate. The highest branching ratios for the weak-annihilation reactions reported here are $\mathcal{B}({\bar{B}}_s^0\to J/\psi \gamma )=1.5\cdot 10^{-7}$ and $\mathcal{B}(B^{-}\to {\bar{D}}_s^{\ast -}\gamma )=1.7\cdot 10^{-7}$, the estimated accuracy of these predictions being at the level of 20\%.

    A Monte Carlo study of double logarithms in the small x region

    G. Chachamis🇪🇸 · A. Sabio Vera🇪🇸

    We investigate the effect of the resummation of collinear double logarithms in the BFKL gluon Green function using the Monte Carlo event generator BFKLex. The resummed collinear terms in transverse momentum space were calculated in Ref. [1] and correspond to the addition to the NLO BFKL kernel of a Bessel function of the first kind whose argument contains the strong coupling and a double logarithm of the ratio of the squared transverse momenta of the reggeized gluons. We discuss how these additional terms improve the collinear convergence of the whole approach and reduce the asymptotic growth with energy of cross sections. Taking advantage of the Monte Carlo implementation, we show how the new results reduce the diffusion of the gluon ladder into infrared and ultraviolet transverse momentum scales, while strongly affecting final state configurations by reducing the mini-jet multiplicity.

    The pi0, eta, eta' -> gamma gamma*(Q^2) Decay Rates and Radii

    A.M.Bernstein🇺🇸

    The low $Q^2$ slopes of the the transition form factors provide a unique method to measure the sizes of the neutral pseudo-scalar mesons, since they do not have electromagnetic form factors. From the slope one obtains the "axial transition RMS radius" $R_{PS,A}=\sqrt{<r^2>}$ for each PS meson. The present status of theory and experiment for these quantities are presented. A comparison of the $R_{PS,A}$ is presented along with the electromagnetic and scalar radii of the ${\pi }^{\pm }$ mesons and the proton. We observe the striking similarity of the values of axial transition radii of all of the pseudoscalar mesons to each other and to the charge radius of the ${\pi }^{\pm }$. In the $Q^2$ = 0 limit the transition form factor is a measure of the pseudo-scalar meson radiative width (lifetime) and is a possible fourth (unexploited) method to perform such a measurement. The ${\pi }^0\to \gamma \gamma$ decay rate is a test of QCD at the confinement scale. There is a firm QCD prediction with a theoretical uncertainty of $\simeq$ 1 \% which calls for an experimental test at the same level of accuracy. There are three methods that have been utilized to perform this measurement and the present status of the experimental tests are outlined. The current accuracy is significantly less than the theoretical uncertainty. The efforts to improve this are briefly summarized.

    Big Bang nucleosynthesis and baryogenesis in power-law $f(R)$ gravity: Revised constraints from the semianalytical approach

    David Wenjie Tian🇨🇦

    In this paper we investigate the primordial nucleosynthesis in $\mathcal{L}={\epsilon }^{2-2\beta }{R}^{\beta }+16\pi m_P^{-2}{\mathcal{L}}_m$ gravity, where $\epsilon$ is a constant balancing the dimension of the field equation, and $1<\beta <(4+\sqrt{6})/5$ for the positivity of energy density and temperature. From the semianalytical approach, the influences of $\beta$ to the decoupling of neutrinos, the freeze-out temperature and concentration of nucleons, the opening of deuterium bottleneck, and the ${}^4$He abundance are all extensively analyzed; then $\beta$ is constrained to $1<\beta <1.05$ for $\epsilon =1$ [1/s] and $1<\beta <1.001$ for $\epsilon =m_P$ (Planck mass). Supplementarily from the empirical approach, abundances of the lightest elements (D, ${}^4$He, ${}^7$Li) are computed by the model-independent best-fit formulae for nonstandard primordial nucleosynthesis, and we find the constraint $1<\beta \le 1.0505$ which corresponds to the extra number of neutrino species $0<\Delta N_{\nu }^{\text{eff}}\le 0.6365$; also, the ${}^7$Li abundance problem cannot be solved by $\mathcal{L}={\epsilon }^{2-2\beta }{R}^{\beta }+16\pi m_P^{-2}{\mathcal{L}}_m$ gravity for this domains of $\beta$. Finally, the consistency with the mechanism of gravitational baryogenesis is estimated.

    What can the CMB tell about the microphysics of cosmic reheating?

    Marco Drewes🇩🇪

    In inflationary cosmology, cosmic reheating after inflation sets the initial conditions for the hot big bang. We investigate how CMB data can be used to study the effective potential and couplings of the inflaton during reheating and constrain the underlying microphysics. If there is a phase of preheating that is driven by a parametric resonance or other instability, then the thermal history and expansion history during the reheating era depend on a large number of microphysical parameters in a complicated way. In this case the connection between CMB observables and microphysical parameters can only established with intense numerical studies. Such studies can help to improve CMB constraints on the effective inflaton potential in specific models, but parameter degeneracies usually make it impossible to extract meaningful best-fit values for individual microphysical parameters. If, on the other hand, reheating is driven by perturbative processes, then it can be possible to constrain the inflaton couplings and the reheating temperature from CMB data. This provides an indirect probe of fundamental microphysical parameters that most likely can never be measured directly in the laboratory, but have an immense impact on the evolution of the cosmos by setting the stage for the hot big bang.

    The curvature of the chiral phase transition line for small values of ${\mu }_B$

    Prasad Hegde🇨🇳 · Heng-Tong Ding (for the Bielefeld-BNL-CCNU collaboration)🇨🇳

    We present preliminary results from an ongoing calculation to determine the curvature of the chiral phase transition line in the chiral limit along the light-light, light-strange and strange-strange chemical potential directions. We do this by studying the appropriate $\mu$-derivatives of the chiral condensate as a function of the quark mass and comparing them to the scaling predictions of $3d$-$O(N)$ theory. We work at a fixed lattice spacing, $N_{\tau }=6$ and at four different quark masses $m_{\pi }\approx$ 140, 110, 90 and 80 MeV. For the light quark curvature, we obtain a value 0.03$⩽{\kappa }_{ll}⩽$0.11. We also find that both strange and light-strange curvatures are around an order of magnitude smaller. Currently, the light-strange curvature is the least constrained curvature and could have either sign, though our results seem to prefer a slightly negative value.

    Axion-photon Propagation in Magnetized Universe

    Chen Wang🇨🇳 · Dong Lai🇺🇸

    Oscillations between photons and axion-like particles (ALP) travelling in intergalactic magnetic fields have been invoked to explain a number of astrophysical phenomena, or used to constrain ALP properties using observations. One example is the anomalous transparency of the universe to TeV gamma-rays. The intergalactic magnetic field is usually modeled as patches of coherent domains, each with a uniform magnetic field, but the field orientation changes randomly from one domain to the next ("discrete-$\phi$ model"). We show in this paper that in more realistic situations, when the magnetic field direction varies continuously along the propagation path, the photon-to-ALP conversion probability $P$ can be significantly different from the discrete-$\phi$ model. In particular, $P$ has a distinct dependence on the photon energy and ALP mass, and can be as large as 100 percent. This result may affect previous constraints on ALP properties based on ALP-photon propagation in intergalactic magnetic fields.

    Non-trivial Center Dominance in High Temperature QCD

    K.-I. Ishikawa🇯🇵 · Y. Iwasaki🇯🇵 · Yu Nakayama🇺🇸 · T. Yoshie🇯🇵

    We investigate the properties of quarks and gluons above the chiral phase transition temperature $T_c,$ using the RG improved gauge action and the Wilson quark action with two degenerate quarks mainly on a $32^3\times 16$ lattice. In the one-loop perturbation theory, the thermal ensemble is dominated by the gauge configurations with effectively $Z(3)$ center twisted boundary conditions, making the thermal expectation value of the spatial Polyakov loop take a non-trivial $Z(3)$ center. This is in agreement with our lattice simulation of high temperature QCD. We further observe that the temporal propagator of massless quarks at extremely high temperature $\beta =100.0(T\simeq 10^{58}{T}_c)$ remarkably agrees with the temporal propagator of free quarks with the $Z(3)$ twisted boundary condition for $t/L_t\ge 0.2$, but differs from that with the $Z(3)$ trivial boundary condition. As we increase the mass of quarks $m_q$, we find that the thermal ensemble continues to be dominated by the $Z(3)$ twisted gauge field configurations as long as $m_q\le 3.0T$ and above that the $Z(3)$ trivial configurations come in. The transition is essentially identical to what we found in the departure from the conformal region in the zero-temperature many-flavor conformal QCD on a finite lattice by increasing the mass of quarks. We argue that the behavior is consistent with the renormalization group analysis at finite temperature.

    Inflation, the scale of supersymmetry breaking, and moduli stabilization

    Emilian Dudas🇫🇷 · Clemens Wieck🇪🇸

    We review the effects of heavy scalar fields during inflation in the framework of $\mathcal{N}=1$ supergravity. Such heavy scalars can be geometric moduli from string compactifications or stabilizer fields from a different sector of the theory. Even when these fields are heavier than the Hubble scale during inflation, they generically cause backreactions which alter the dynamics of the system. Severe problems may arise when the heavy fields break supersymmetry, which is quite generic for Kähler moduli. We illustrate these effects in two examples, chaotic inflation and Starobinsky-like inflation. In chaotic inflation the backreaction of heavy Kähler moduli causes a flattening of the quadratic potential. In many setups of Starobinsky-like inflation, however, backreactions spoil the flatness of the plateau.

    The quest for dark matter with neutrino telescopes

    Carlos Pérez de los Heros🇸🇪

    There should be not doubt by now that neutrino telescopes are competitive instruments when it comes to searches for dark matter. Their large detector volumes collect hundreds of neutrinos per day. They scrutinize the whole sky continuously, being sensitive to neutrino signals of all flavours from dark matter annihilations in nearby objects (Sun, Earth, Milky Way Center and Halo) as well as from far away galaxies or galaxy clusters, and over a wide energy range. In this review we summarize the analysis techniques and recent results on dark matter searches from the neutrino telescopes currently in operation.
