| Abstract: A measurement of the inclusive cross section for the process pp to b b-bar X to muon muon X' at $\sqrt{s}$ = 7 TeV is presented, based on a data sample corresponding to an integrated luminosity of 27.9 inverse picobarns collected by the CMS experiment at the LHC. By selecting pairs of muons each with pseudorapidity abs(eta)<2.1, the value of the cross section for pp to b b-bar X to muon muon X' is found to be 25.7 +/- 0.1 (stat.) +/- 2.2 (syst.) +/- 1.0 (lumi.) nb is obtained for muons with transverse momentum greater than 4 GeV, and 5.03 +/- 0.05 (stat.) +/- 0.46 (syst.) +/- 0.20 (lumi.) nb for transverse momenta greater than 6 GeV. These results are compared to QCD predictions at leading and next-to-leading orders. | ||
