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 13 TeV, corresponding to an integrated luminosity of 137 fb^-1 . The Higgs boson transverse momentum (pT) is reconstructed using the lepton pair pT and missing pT. The number of jets is defined in accortance with STXS jet definition. The differential cross section times branching fraction is measured as a function of the Higgs boson pT and number of jets in a fiducial phase space defined to match the experimental acceptance in terms of the lepton kinematics and event topology. Results are unfolded to particle level The fiducial region is defined at particle level (using Born level leptons) as: - emununu - leading lepton pT > 25 GeV - subleading lepton pT > 13 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) > 60 GeV - Invariant mass of the subleading lepton and the neutrinos in the transverse plane mT_l2 > 30 GeV
