Abstract (data abstract)
CERN-LHC. Measurements of the double-differential Drell-Yan cross sections are presented using an integrated luminosity of 19.7 inverse femtobarns in the dimuon channel of proton-proton collision data recorded in 2012 with the CMS detector at the LHC at sqrt(s) = 8 TeV. Covariance matrices are provided in addition to the tables given in the paper.
