摘要: A measurement of W boson production in lead-lead collisions at root s(NN) = 2.76 TeV is presented. It based on the analysis data collected with ATLAS detector LHC 2011 corresponding to an integrated luminosity 0.14 nb(-1) and 0.15 muon electron decay channels, respectively. The differential yields lepton charge asymmetry are each measured as a function average number participating nucleons absolute pseudorapidity charged lepton. results compared predictions next-to-leading-order QCD calculations. These measurements are, principle, sensitive possible nuclear modifications parton distribution functions also provide information scaling multi-nucleon systems.
