Abstract (data abstract)
CERN-LHC. This paper describes a measurement of fiducial and differential cross sections of gluon-fusion Higgs boson production in the H->WW*->e nu mu nu channel, using 20.3 fb^{-1} of proton--proton collision data. The data were produced at a centre-of-mass energy of sqrt(s) = 8 TeV at the CERN Large Hadron Collider and recorded by the ATLAS detector in 2012. Cross sections are measured from the observed H->WW*->e nu mu nu signal yield in categories distinguished by the number of associated jets. The total cross section is measured in a fiducial region defined by the kinematic properties of the charged leptons and neutrinos. Differential cross sections are reported as a function of the number of jets, the Higgs boson transverse momentum, the dilepton rapidity, and the transverse momentum of the leading jet. The jet-veto efficiency, or fraction of events with no jets above a given transverse momentum threshold, is also reported. All measurements are compared to QCD predictions from Monte Carlo generators and fixed-order calculations, and are in agreement with the Standard Model predictions. The fiducial region is defined as: - 1 electron, 1 muon, 2 neutrinos, n jets - electron: pT> 15 GeV, |eta|< 1.37 or 1.52< |eta|< 2.47 - muon: pT> 15 GeV, |eta|< 2.5 - jets: pT> 25 GeV if |eta|< 2.4, pT> 30 GeV if 2.4 <|eta|< 4.5 - leading lepton: pT> 22 GeV - 10 < M(e,mu) < 55 GeV - Delta_Phi(e,mu) < 1.8 - missing transeverse momentum > 20 GeV.
