Measurement of the production and lepton charge asymmetry of W bosons in Pb+Pb collisions at √sNN = 2.76 TeV with the ATLAS detector

A measurement of W boson production in lead-lead collisions at √sNN = 2.76 TeV is presented. It is based on the analysis of data collected with the ATLAS detector at the LHC in 2011 corresponding to an integrated luminosity of 0.14 nb -1 and 0.15 nb -1 in the muon and electron decay channels, respec...
