Measurement of the transverse momentum spectrum of the Higgs boson produced in pp collisions at √s=8 TeV using H → WW decays
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...

| Summary: | 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. |
