Study of final-state radiation in decays of Z bosons produced in pp collisions at 7 TeV
(2015)Physical Review DThe differential cross sections for the production of photons in Z→μ+μ−γ decays are presented as a function of the transverse energy of the photon and its separation from the nearest muon. The data for these measurements are collected with the CMS detector and correspond to an integrated luminosity of 4.7 fb−1 of pp collisions at √s=7 TeV delivered by the CERN LHC. The cross sections are compared to simulations with powheg and pythia, ...Journal Article
