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 ... -
Markov-Nash equilibria in mean-field games with discounted cost
(Society for Industrial and Applied Mathematics Publications, 2018)In this paper, we consider discrete-time dynamic games of the mean-field type with a finite number $N$ of agents subject to an infinite-horizon discounted-cost optimality criterion. The state space of each agent is a Polish ... -
Mass and pole residue of Yb(10890) state with JPC = 1−− at finite temperature
(AIP Publishing, 2019)The status of the hidden beauty state Y-b is not clear up to now. The deviations from the expected behavior can provide a clue to consider it as an exotic meson candidate. Assuming the Y-b resonance as a tetraquark, we ... -
Mean field multilayer stackelberg differential games in multi-agent systems
(Ministry Communications & High Technologies Republic Azerbaijan, 2018)In this paper, we study linear-quadratic hierarchical mean field Stackelberg differential games with decentralized adapted open-loop information structure. In this game model, there are three levels of decision making, ... -
