Investigating the violation of charge-parity symmetry through top-quark chromoelectric dipole moments by using machine learning techniques
(Jagiellonian University, 2023)There are a number of studies in the literature on the search for Charge- Parity (CP) violating signals in top-quark productions at the LHC. In most of these studies, ChromoMagnetic Dipole Moments (CMDM) and ChromoElectric ... -
Investigation into the event-activity dependence of ϒ(nS) relative production in proton-proton collisions at s√ = 7 TeV
(Springer Nature, 2020-11-02)The ratios of the production cross sections between the excited gamma(2S) and gamma(3S) mesons and the gamma(1S) ground state, detected via their decay into two muons, are studied as a function of the number of charged ... -
Investigation of the excited states in hidden charm hidden strange sector
(2018)In this work, we studied the radial excitations of X(4140) and like states within QCD sum rules. We chose three molecular and three diquark-antidiquark currents with the quark content cc‾ss‾ and JPC = 0++, 1++, 2++, and ... -
Jet and underlying event properties as a function of charged-particle multiplicity in proton–proton collisions at TeX
(Springer Science+Business Media, 2013-12)Characteristics of multi-particle production in proton-proton collisions at root s = 7 TeV are studied as a function of the charged-particle multiplicity, N (ch). The produced particles are separated into two classes: those ... -
Jet energy scale and resolution in the CMS experiment in pp collisions at 8 TeV
(IOP , 2017)Improved jet energy scale corrections, based on a data sample corresponding to an integrated luminosity of 19.7 fb-1 collected by the CMS experiment in proton-proton collisions at a center-of-mass energy of 8 TeV, are ... -
Jet shapes of isolated photon-tagged jets in Pb-Pb and pp collisions at √sNN = 5.02 TeV
(American Physical Society, 2019-04-17)The modification of jet shapes in Pb-Pb collisions, relative to those in pp collisions, is studied for jets associated with an isolated photon. The data were collected with the CMS detector at the LHC at a nucleon- nucleon ... -
Kerr–Newman black holes can be generically overspun
(Springer Nature, 2019-04-08)We construct thought experiments involving the perturbations of Kerr-Newman black holes by neutral test fields to evaluate the validity of the weak form of the cosmic censorship conjecture. We first show that neglecting ... -
Large deviations for local mass of branching Brownian motion
(Instituto Nacional de Matematica Pura e Aplicada, 2020)We study the local mass of a dyadic branching Brownian motion Z evolving in R-d. By 'local mass', we refer to the number of particles of Z that fall inside a ball with fixed radius and time-dependent center, lying in the ... -
Large deviations principle for discrete-time mean-field games
(Springer, 2021-11)In this paper, we establish a large deviations principle (LDP) for interacting particle systems that arise from state and action dynamics of discrete-time mean-field games under the equilibrium policy of the infinite-population ... -
Learning in discrete-time average-cost mean-field games
(IEEE, 2021)In this paper, we consider learning of discrete-time mean-field games under an average cost criterion. We propose a Q-iteration algorithm via Banach Fixed Point Theorem to compute the mean-field equilibrium when the model ... -
Learning mean-field games with discounted and average costs
(Microtome Publishing, 2023)We consider learning approximate Nash equilibria for discrete-time mean-field games with stochastic nonlinear state dynamics subject to both average and discounted costs. To this end, we introduce a mean-field equilibrium ... -
LHC constraints on color octet scalars
(American Physical Society, 2017-08-09)We extract constraints on the parameter space of the Manohar and Wise model by comparing the cross sections for dijet, top-pair, dijet-pair,t (t) over bart (t) over bar and b (b) over barb (b) over bar productions at the ... -
LHC constraints on W′, Z′ that couple mainly to third generation fermions
(Springer Nature, 2020-11-03)We use the results of CMS and ATLAS searches for resonances that decay to tau nu or tb and tau(+)tau(-) or t (t) over bar final states to constrain the parameters of non-universal W' and Z' gauge bosons that couple ... -
Light D-wave axial-tensor K2(1820) meson at finite temperature
(IOP Publishing, 2019-06)In this work the properties of the axial-tensor K-2(1820) meson in a hot medium are investigated. The mass and the decay constant of this state are calculated via thermal QCD sum rules considering QCD condensates up to ... -
Limits on the Higgs boson lifetime and width from its decay to four charged leptons
(American Physical Society, 2015-10-01)Constraints on the lifetime and width of the Higgs boson are obtained from H→ZZ→4ℓ events using data recorded by the CMS experiment during the LHC run 1 with an integrated luminosity of 5.1 and 19.7 fb−1 at a center-of-mass ... -
Local existence of solutions to the initial-value problem for one-dimensional strain-limiting viscoelasticity
(Elsevier, 2020-11-15)In this work we prove local existence of strong solutions to the initial-value problem arising in one-dimensional strain-limiting viscoelasticity, which is based on a nonlinear constitutive relation between the linearized ... -
Long-range two-particle correlations of strange hadrons with charged particles in pPb and PbPb collisions at LHC energies

Long-time existence of solutions to nonlocal nonlinear bidirectional wave equations
(American Institute of Mathematical Sciences, 2019-05)We consider the Cauchy problem defined for a general class of nonlocal wave equations modeling bidirectional wave propagation in a nonlocally and nonlinearly elastic medium whose constitutive equation is given by a convolution ... -
A look inside charmed-strange baryons from lattice QCD
(American Physical Society, 2015-12-01)The electromagnetic form factors of the spin-3/2 Ω baryons, namely Ω, Ω∗c, Ω∗cc and Ωccc, are calculated in full QCD on 323×64 PACS-CS lattices with a pion mass of 156(9) MeV. The electric charge radii and magnetic moments ... -
Lump solutions of the fractional Kadomtsev–Petviashvili equation
(Springer, 2024-01)Of concern is the fractional Kadomtsev–Petviashvili (fKP) equation and its lump solution. As in the classical Kadomtsev–Petviashvili equation, the fKP equation comes in two versions: fKP-I (strong surface tension case) and ...
