Abstract
We report on the first measurements of J/ψ, W and Z boson production in lead–lead collisions measured by the ATLAS detector at the nucleon–nucleon centre of mass energy TeV. These measurements are performed via the J/ψ and electroweak boson decays to muon final states. We present a measurement of W boson yields produced in heavy-ion collisions as function of centrality, ratios of W+/W− and W/Z. For a subset of the W → μν decays, we report on muon rapidity and charge asymmetry measurements. These measurements are the first ATLAS results on W measurements in lead–lead collisions at the LHC.
