Measurement of the differential and double-differential Drell-Yan cross section in proton-proton collisions at 7 TeV

2013

Abstract: Measurements are presented for the measurements of the differential and double differential Drell-Yan cross section using anintegrated luminosity of .5 $~fb$ ^{-1} $(dimuon) and .8$ ~fb $^{-1}$ (dielectron) of proton-proton collision data recorded with the CMS detector at the LHC at $\sqrt{s} = 7$ ~TeV. The cross sections $d\sigma/dM$ are measured in the mass range $~GeV to$ ~GeV for the dimuon, dielectron, and combined channels. Results are also presented on the measurement of the double-differential cross section $d^2\sigma/dMdY$ in the dimuon channel. The double-differential cross section measurement is performed over the mass range $~GeV to$ ~GeV and absolute dimuon rapidity from $to .4$ . The differential cross section measurements are normalized to the $Z$ -peak region ( - 120$~GeV) to achieve better accuracy. The measurements are compared to the predictions of perturbative QCD calculations at next-to-leading and next-to-next-to-leading order using various sets of parton distribution functions.
