Abstract: A study of W production via the muon decay channel in lead-lead collisions at s NN − − − √ =2.76 TeV is presented using data corresponding to an integrated luminosity of 0.14 nb −1 collected with the ATLAS detector at the Large Hadron Collider in 2011. The production rates are measured in a fiducial kinematic range as a function of the average number of participating nucleons ⟨N part ⟩ and absolute psuedorapidity. A measurement of the muon charge asymmetry as a function of absolute pseudorapidity is presented as well. The results are compared to predictions based on modified leading order and next to leading order calculations with the MRSTLO* and MSTW2008NLO parton distribution functions. This measurement provides information on the binary scaling of W production in multi-nucleon systems as well as possible modifications to the parton distribution functions
