BFKL Pomeron and the survival factorFeb 21 2019We consider the absorptive corrections and the rapidity gap survival factor which are necessary to provide the unitarization of the BFKL Pomeron. In particular we discuss the role of the enhanced screening diagrams. Exclusive vector meson production in heavy ion collisionsFeb 21 2019We discuss the salient features of exclusive vector meson production in heavy ion collisions at LHC energies. Special attention is paid to the space-time picture of the process. We account for both coherent and incoherent contributions. The explicit quantitative ... More Continuous symmetries and approximate quantum error correctionFeb 20 2019Quantum error correction and symmetry arise in many areas of physics, including many-body systems, metrology in the presence of noise, fault-tolerant computation, and holographic quantum gravity. Here we study the compatibility of these two important ... More Negative temperature in CPT-symmetic UniverseFeb 20 2019In Ref.1 (L. Boyle, K. Finn and N. Turok, CPT-Symmetric Universe, Phys. Rev. Lett. {\bf 121}, 251301 (2018)) the antispacetime Universe was suggested as the analytic continuation of our Universe across the Big Bang singularity. We extended this analytic ... More More five-parameter models for lepton mixingFeb 20 2019We propose four new lepton-mixing textures that may be enforced through well-defined symmetries in renormalizable models. Each texture has only five parameters to predict nine observables; the textures are therefore able to produce testable predictions ... More Strong Decays of observed $Λ_c$ Baryons in the $^3P_0$ ModelFeb 20 2019The strong decay widths and some important branching ratios of possible Okubo-Zweig-Iizuka(OZI)-allowed strong decay channels of $\Lambda_c(2595)^+$, $\Lambda_c(2625)^+$, $\Lambda_c(2765)^+$ ($\Sigma_c(2765)^+$), $\Lambda_c(2860)^+$, $\Lambda_c(2880)^+$ ... More Conference Summary of QNP2018Feb 20 2019This report is the summary of the Eighth International Conference on Quarks and Nuclear Physics (QNP2018). Hadron and nuclear physics is the field to investigate ultimate high-density quantum many-body systems bound by strong interactions. It is intended ... More Simplest Radiative Dirac Neutrino Mass ModelsFeb 19 2019If neutrinos are Dirac particles, their right-handed partners must be present in the theory. Once introduced in the Standard Model (SM), the difference between the baryon number $B$ and the lepton number $L$ can be promoted to a local $U(1)_{B-L}$ symmetry ... More Scalar DemocracyFeb 19 2019We conjecture that there exists a scalar bound state for every pair of fundamental fermions at a UV (`composite') scale, $\Lambda\gg v_{\text{weak}}$. This implies a large number of universally coupled, sub-critical Higgs doublets. All but the Standard ... More Entropies for Coupled Harmonic Oscillators and TemperatureFeb 19 2019We study two entropies of a system composed of two coupled harmonic oscillators which is brought to a canonical thermal equilibrium with a heat-bath at temperature $T$. Using the purity function, we explicitly determine the R\'enyi and van Newmon entropies ... More Thermal emission from semi-classical dynamical systemFeb 19 2019Recently the bound on the Lyapunov exponent $\lambda_L \le 2\pi T/ \hbar$ in thermal quantum systems was conjectured by Maldacena, Shenker and Stanford. If we naively apply this bound to a system with a fixed Lyapunov exponent $\lambda_L$, it might predict ... More Light scalars in composite Higgs modelsFeb 19 2019A composite Higgs boson is likely to be accompanied by additional light states generated by the same dynamics. This expectation is substantiated when realising the composite Higgs mechanism by an underlying gauge theory. We review the dynamics of such ... More Spinning extensions of $D(2,1;α)$ superconformal mechanicsFeb 19 2019As is known, any realization of SU(2) in the phase space of a dynamical system can be generalized to accommodate the exceptional supergroup $D(2,1;\alpha)$, which is the most general $\mathcal{N}{=}\,4$ supersymmetric extension of the conformal group ... More Measurement of b-hadron fractions in 13 Tev pp collisionsFeb 18 2019The production fractions of $\overline{B}_s^0$ and $\Lambda_b^0$ hadrons, normalized to the sum of $B^-$ and $\overline{B}^0$ fractions, are measured in 13 TeV pp collisions using data collected by the LHCb experiment, corresponding to an integrated luminosity ... More Measurement of b-hadron fractions in 13 TeV pp collisionsFeb 18 2019Feb 20 2019The production fractions of $\overline{B}_s^0$ and $\Lambda_b^0$ hadrons, normalized to the sum of $B^-$ and $\overline{B}^0$ fractions, are measured in 13 TeV pp collisions using data collected by the LHCb experiment, corresponding to an integrated luminosity ... More Charged spherically symmetric black holes in $f(R)$ gravityFeb 18 2019A new class of analytic charged spherically symmetric black hole solutions, which behave asymptotically as flat or (A)dS spacetimes, is derived for specific classes of $f(R)$ gravity, i.e., $f(R)=R-2\alpha\sqrt{R}$ and $f(R)=R-2\alpha\sqrt{R-8\Lambda}$, ... More Naturalness without new particlesFeb 18 2019We demonstrate that the physics which resolves naturalness problems need not take the form of new particles and can sometimes manifest itself as higher dimensional operators. As a proof of principle, we present a simple model where the scale of new particles ... More ECO-like behavior in black hole analoguesFeb 18 2019Classical phenomenological aspects of acoustic perturbations on a draining bathtub geometry where a surface with reflectivity $\mathcal{R}$ is set at a small distance from the would-be acoustic horizon, which is excised, are addressed. A low-frequency ... More Seeing in complete darkness, using the Unruh effectFeb 18 2019We present a new method by which, in principle, it is possible to "see in absolute darkness", i.e., without exchanging any real quanta through quantum fields. This is possible because objects modify the mode structure of the vacuum in their vicinity. ... More Anomalous SupersymmetryFeb 18 2019We show that supersymmetry is anomalous in ${\cal N}=1$ superconformal quantum field theories (SCFTs) with an anomalous R-symmetry. This anomaly was originally found in holographic SCFTs at strong coupling. Here we show that this anomaly is present in ... More Round Table on Axions and Axion-like ParticlesFeb 18 2019In this contribution, based on the discussion at a round table of the XIII Quark Confinement and the Hadron Spectrum - Confinement conference, we review the main properties of the QCD axion and, more generally, of axion-like particles and their relevance ... More Bounce cosmology in generalized modified gravitiesFeb 18 2019We investigate the bounce realization in the framework of generalized modified gravities arising from Finsler and Finsler-like geometry. In particular, the richer intrinsic geometrical structure is reflected in the appearance of extra degrees of freedom ... More No-go theorem for asymptotically AdS static regular boson starsFeb 18 2019In a recent paper, Hod has proven no-go theorem for asymptotically flat static regular boson stars. In the present work, we extend discussions to the gravity with a negative cosmological constant. In the asymptotically AdS background, we show that spherically ... More An inverse seesaw model with global $U(1)_H$ symmetryFeb 17 2019We propose an inverse seesaw model based on hidden global symmetry $U(1)_H$ in which we realize tiny neutrino masses with rather natural manner taking into account relevant experimental bounds. The small Majorana mass for inverse seesaw mechanism is induced ... More Asymmetries of anti-triplet charmed baryon decaysFeb 17 2019We analyze the decay processes of ${\bf B}_c \to {\bf B}_n M$ with the $SU(3)_F$ flavor symmetry and spin-dependent amplitudes, where ${\bf B}_c({\bf B}_n)$ and $M$ are the anti-triplet charmed (octet) baryon and nonet meson states, respectively. In the ... More IceCube Sterile Neutrino SearchesFeb 17 2019Anomalies in short baseline experiments have been interpreted as evidence for additional neutrino mass states with large mass splittings from the known, active flavors. This explanation mandates a corresponding signature in the muon neutrino disappearance ... More On DUNE prospects in the search for sterile neutrinosFeb 16 2019Experiments measuring the parameters of active neutrino oscillations can also search for sterile neutrinos in a part of sterile neutrino parameter space. In this paper we analyze the sensitivity of the upcoming experiment DUNE to the active-sterile neutrino ... More A new approach to gauge coupling unification and proton decayFeb 16 2019A novel analytical formalism is proposed, linking the supersymmetric and GUT spectra in any GUT model in which the three gauge couplings unify. In each specific GUT model, one can then fully explore the interplay between the pattern of supersymmetry breaking ...

It combines the postulates of local quantum physics, encoded in the Haag-Kastler axioms, with insights gained in the perturbative approach to quantum ... More Fermion Conformal Bootstrap in 4dFeb 15 2019We apply numerical conformal bootstrap techniques to the four-point function of a Weyl spinor in 4d non-supersymmetric CFTs. We find universal bounds on operator dimensions and OPE coefficients, including bounds on operators in mixed symmetry representations ... More Scotogenic dark matter stability from gauged matter parityFeb 15 2019We explore the idea that dark matter stability results from the presence of a matter-parity symmetry, arising naturally as a consequence of the spontaneous breaking of an extended $\mathrm{SU(3) \otimes SU(3)_L \otimes U(1)_X \otimes U(1)_{N}}$ electroweak ... More Safe ClockworkFeb 15 2019In this letter we demonstrate that safe quantum field theories can accommodate the clockwork mechanism upgrading it to a fundamental theory a l\'a Wilson. Additionally the clockwork mechanism naturally sources Yukawa hierarchies for safe completions of ... More The Axidental UniverseFeb 15 2019Theories with several hundred axion fields have enormous numbers of distinct meta-stable minima. A small fraction of these local minima have vacuum energy compatible with current measurements of dark energy. The potential also contains regions suitable ... More Which EFTFeb 15 2019We classify effective field theory (EFT) deformations of the Standard Model (SM) according to the analyticity property of the Lagrangian as a function of the Higgs doublet H. Our distinction in analytic and non-analytic corresponds to the more familiar ... More Coset CosmologyFeb 15 2019We show that the potential of Nambu-Goldstone bosons can have two or more local minima e.g. at antipodal positions in the vacuum manifold. This happens in many models of composite Higgs and of composite Dark Matter. Trigonometric potentials lead to unusual ... More Viable inflationary magnetogenesis with helical couplingFeb 15 2019We consider helical coupling to electromagnetism and present a simple model of evolution of the coupling function leading to a viable inflationary magnetogenesis. In this scenario, helical magnetic fields of any desirable strength of order up to $10^{- ... More Anisotropic $2$-form dark energyFeb 15 2019We study the dynamics of dark energy in the presence of a 2-form field coupled to a canonical scalar field $\phi$. We consider the coupling proportional to $e^{-\mu \phi/M_{\rm pl}} H_{\alpha \beta \gamma}H^{\alpha \beta \gamma}$ and the scalar potential ... More Causally neutral quantum physicsFeb 15 2019In fundamental theories that accounts for quantum gravitational effects, the spacetime causal structure is expected to be quantum uncertain. Previous studies of quantum causal structure focused on finite-dimensional systems. Here we present an algebraic ... More Exploring SMEFT in VH with Machine LearningFeb 15 2019In this paper we study the use of Machine Learning techniques to exploit kinematic information in VH, the production of a Higgs in association with a massive vector boson. We parametrise the effect of new physics in terms of the SMEFT framework. We find ... More Feynman's different approach to electrodynamicsFeb 15 2019We discuss a previously unpublished description of electromagnetism developed by Richard P. Feynman in the 1960s. Though similar to the existing approaches deriving electromagnetism from special relativity, the present one extends a long way towards the ...

In an effective Lagrangian approach, the branching ratios of $B_c^+ \to Z_c(3900)^+ \pi^0$ and $B_c^+\to Z_c (4020)^+ \pi^0$ are estimated ... More Nuclear Transparency in Monte Carlo Neutrino Event GeneratorsFeb 14 2019Hadron cascade model is an essential part of Monte Carlo neutrino event generators that governs final state interactions of knocked-out nucleons and produced pions. It is shown that such model enriched with physically motivated modifications of nucleon-nucleon ... More Elastic and diffractive scattering in the LHC eraFeb 14 2019We review elastic and diffractive scattering of protons (called also "forward physics") with emphasis on the LHC data, especially those deviating from the expectations based on extrapolations from earlier measurements at the ISR, Fermilab and thus triggering ... More The Higgs Trilinear Coupling and the Scale of New PhysicsFeb 14 2019We consider modifications of the Higgs potential due to new physics at high energy scales. These upset delicate cancellations predicted by the Standard Model for processes involving Higgs bosons and longitudinal gauge bosons, and lead to a breakdown of ... More Searching for heavy neutrinos with WWH productionFeb 14 2019Extensions of the Standard Model are required to give mass to the light neutrinos and explain neutrino oscillations. One of the simplest ideas is to introduce new heavy, gauge singlet fermions that play the role of right-handed neutrinos in a seesaw mechanism. ... More Disorder and Mimesis at Hadron CollidersFeb 14 2019We discuss how systems with a large number of degrees of freedom and disorder in their mass matrix can play a role in particle physics. We derive results on their mass spectra using, where applicable, QFT techniques. We study concrete realizations of ... More
