We report on the first measurements of J/psi, W and Z boson production in lead-lead collisions measured by the ATLAS detector at the nucleon-nucleon centre of mass energy sqrt{s_{NN}} = 2.76 TeV. These measurements are done via the muon decay of J/psi and electroweak bosons. We present a measurement...

description We report on the first measurements of J/psi, W and Z boson production in lead-lead collisions measured by the ATLAS detector at the nucleon-nucleon centre of mass energy sqrt{s_{NN}} = 2.76 TeV. These measurements are done via the muon decay of J/psi and electroweak bosons. We present a measurement of W bosons 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.
