Özet
A measurement of the inclusive cross section for the process pp->bbarX->mumuX' at sqrt(s) = 7TeV is presented, based on a data sample corresponding to an integrated luminosity of 27.9 pb-1 collected by the CMS experiment at the LHC. By selecting pairs of muons each with pseudorapidity jj < 2:1, the value (pp ! bbX ! X0) = 26:4 0:1 (stat.) 2:4 (syst.) 1:1 (lumi.) nb is obtained for muons with transverse momentum pT > 4 GeV, and 5:120:03 (stat.) 0:48 (syst.) 0:20 (lumi.) nb for pT > 6 GeV. These results are compared to QCD predictions at leading and next-to-leading orders.
