Abstract (data abstract)
CERN-LHC.The cross section for Higgs boson production in pp collisions is studied using the H -> W + W - decay mode, followed by leptonic decays of the W bosons to an oppositely charged electron-muon pair in the final state. The measurements are performed using data collected by the CMS experiment at the LHC at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.4 fb^-1 . The Higgs boson transverse momentum (pT) is reconstructed using the lepton pair pT and missing pT . The differential cross section times branching fraction is measured as a function of the Higgs boson pT in a fiducial phase space defined to match the experimental acceptance in terms of the lepton kinematics and event topology. The production cross section times branching fraction in the fiducial phase space is measured to be 39 +/- 8 (stat) +/- 9 (syst) fb. The measurements are found to agree, within experimental uncertainties, with theoretical calculations based on the standard model. The fiducial region is defined at particle level (using Born level leptons) as: - emununu - leading lepton pT > 20 GeV - subleading lepton pT > 10 GeV - psudorapidity of electrons and muons |eta| < 2.5 - Invariant mass of the two charged leptons mll > 12 GeV - Charged lepton pair pT > 30 GeV - Invariant mass of the leptonic system in the transverse plane mT(emununu) > 50 GeV
