Subdiffusivity of brownian motion among a poissonian field of moving traps
(Instituto Nacional de Matematica Pura e Aplicada, 2019)Our model consists of a Brownian particle X moving in N, where a Poissonian field of moving traps is present. Each trap is a ball with constant radius, centered at a trap point, and each trap point moves under a Brownian ... -
Suppression and azimuthal anisotropy of prompt and nonprompt J/psi production in PbPb collisions at root S-NN=2.76 TeV
(Springer International Publishing, 2017-04)The nuclear modification factor R-AA and the azimuthal anisotropy coefficient v(2) ofprompt and nonprompt (i.e. those from decays of b hadrons) J/psi mesons, measured from PbPb and pp collisions at root S-NN = 2.76 rfeV ... -
Suppression of excited Υ states relative to the ground state in Pb-Pb collisions at √sNN =5.02 TeV
(American Physical Society, 2018-04-02)The relative yields of gamma mesons produced in pp and Pb-Pb collisions at root s(NN) = 5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are ... -

(Elsevier, 2017)The production yields of ϒ(1S), ϒ(2S), and ϒ(3S) quarkonium states are measured through their decays into muon pairs in the CMS detector, in PbPb and pp collisions at the centre-of-mass energy per nucleon pair of 2.76 ... -
Survival of branching Brownian motion in a uniform trap field
(Elsevier, 2016-03)We study a branching Brownian motion Z evolving in Rd, where a uniform field of Poissonian traps are present. We consider a general offspring distribution for Z and find the asymptotic decay rate of the annealed survival ... -
T-odd correlations from the top-quark chromoelectric dipole moment in lepton plus jets top-pair events
(American Physical Society, 2016-01-01)There exist several recent studies of the top-quark chromoelectric dipole moment (CEDM) in the context of searching for charge parity violating signals in top-quark pair production at the LHC. Most of these studies constrain ... -
Technical note: Application of an optical hydrophone to ionoacoustic range detection in a tissue-mimicking agar phantom
(Wiley, 2023-12)Background: Ionoacoustics is a promising approach to reduce the range uncertainty in proton therapy. A miniature-sized optical hydrophone (OH) was used as a measuring device to detect weak ionoacoustic signals with a high ... -
Testing cosmic censorship conjecture for extremal and near-extremal (2 + 1)-dimensional MTZ black holes
(IOP Publishing, 2020-09-03)We test the validity of the weak cosmic censorship conjecture for the (2 + 1)-dimensional charged anti-de Sitter black hole solution, which was derived by Martinezet al(MTZ). We first construct a thought experiment by ... -
Tests of CMS hadron forward calorimeter upgrade readout box prototype
(IOP Publishing, 2012-10)A readout box prototype for the CMS Hadron Forward calorimeter upgrade was built and tested in the CERN H2 beamline. The prototype was designed to enable simultaneous tests of different readout options for the four anode ... -
Theoretical determination of K(1)(1270,1400) mixing angle in QCD
(IOP Publishing, 2012)In quark model, the strange axial vector mesons K1(1270) and K1(1400) are defined as the mixtures of orbital angular momentum states K1A and K1B. In this work, by using the orthogonality of the mass eigenstates, we have ... -
A thermodynamically consistent stress-rate type model of one-dimensional strain-limiting viscoelasticity
(Springer Nature, 2020-05-28)We introduce a one-dimensional stress-rate type nonlinear viscoelastic model for solids that obey the assumptions of the strain-limiting theory. Unlike the classical viscoelasticity theory, the critical hypothesis in the ... -

Top-quark forward-backward asymmetry from a color-octet t-channel resonance
(American Physical Society, 2014-05-09)We consider new physics contributions to the top-quark forward-backward asymmetry from a neutral V-8(0) or charged V-8(+) color-octet vector exchanged in the t channel. We study the phenomenological constraints on these ... -
A topology for policies in decentralized stochastic control and existence of optimal policies
(IEEE, 2018)In this paper, we introduce a topology for policies in decentralized stochastic control models to establish the existence of team-optimal policies for both static and a class of sequential dynamic teams. We first consider ... -
A topology for team policies and existence of optimal team policies in stochastic team theory
(IEEE, 2020-01)In this paper, we establish the existence of team-optimal policies for static teams and a class of sequential dynamic teams. We first consider the static team problems and show the existence of optimal policies under certain ... -
Transverse linear instability of solitary waves for coupled long-wave-short-wave interaction equations

Traveling waves and transverse instability for the fractional Kadomtsev–Petviashvili equation
(Wiley, 2022-07)Of concern are traveling wave solutions for the fractional Kadomtsev–Petviashvili (fKP) equation. The existence of periodically modulated solitary wave solutions is proved by dimension-breaking bifurcation. Moreover, the ... -
