Abstract

The precision measurement of the differential Drell-Yan cross section dσ/dM and the first measurement of the double differential cross section d^2σ/dMdY at √s = 7 TeV are presented. A dataset of 4.7 fb-1 of pp collisions collected with the CMS detector at the LHC during the year 2011 was used for these measurements. The dσ/dM cross section was measured in the dimuon channel in the invariant mass range 15 GeV to 1.5 TeV. A substantially improved precision compared to the previous measurements has been achieved. The d2σ/dMdY cross section measurement has been performed in the dimuon invariant mass range from 15 GeV to 1 TeV covering the dimuon rapidity range from -2.5 to 2.5. Both measurements were found to be in good agreement with theoretical predictions estimated using the NNLO MSTW2008 PDFs.
