(Springer, 2014-03)Double parton scattering is investigated in proton-proton collisions at √s = 7 TeV where the final state includes a W boson, which decays into a muon and a neutrino, and two jets. The data sample corresponds to an integrated ... -
Study of exclusive two-photon production of W+W- in pp collisions at √s=7 TeV and constraints on anomalous quartic gauge couplings
(Springer, 2013)A search for exclusive or quasi-exclusive W+W- production by photon-photon interactions, pp → p(*)W +W-p(*), at √s=7 TeV is reported using data collected by the CMS detector with an integrated luminosity of 5.05 fb-1. ... -
Study of hadronic event-shape variables in multijet final states in pp collisions at √s = 7 tev
(Springer, 2014)Event-shape variables, which are sensitive to perturbative and nonperturbative aspects of quantum chromodynamic (QCD) interactions, are studied in multijet events recorded in proton-proton collisions at √s = 7TeV. Events ... -
Study of jet quenching with Z+jet correlations in Pb-Pb and pp collisions at s NN=5.02 TeV
(American Physical Society, 2017-08)The production of jets in association with Z bosons, reconstructed via the μ+μ- and e+e- decay channels, is studied in pp and, for the first time, in Pb-Pb collisions. Both data samples were collected by the CMS experiment ... -

Traveling wave solutions for nonlinear differential-difference equations of rational types
(Institute of Physics Publishing, 2016-01-01)Differential-difference equations are considered to be hybrid systems because the spatial variable n is discrete while the time t is usually kept continuous. Although a considerable amount of research has been carried out ... -
