Cross section as a function of pT and y of the Z boson decaying into muons in p p collisions at √s = 7 TeV. pT and y cross sections are measured for 60<mμμ<120 GeV. The pT cross section is measured for lepton pT>20 GeV and η<2.1, while the y cross section is extrapolated to all lepton pT and η. This measurement was performed using 36 pb−1 of data collected during 2010 with the CMS detector at the LHC.
