Measurement of Z boson production in Pb-Pb collisions at √S NN = 2.76 TeV with the ATLAS detector

The ATLAS experiment has observed 1995 Z boson candidates in data corresponding to 0:15 nb -1 of integrated luminosity obtained in the 2011 LHC Pb + Pb run at √S NN = 2.76 TeV. The Z bosons are reconstructed via dielectron and dimuon decay channels, with a background contamination of less than 3%. R...
