Abstract (data abstract)
CERN-LHC. Constraints of Higgs boson production with transverse momentum up to the TeV scale. The analyzed pp collision data were recorded with the ATLAS detector at the LHC with a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of 136 fb^-1. Higgs bosons decaying to bb are reconstructed as single large-radius jets and identified by the experimental signature of two b-hadron decays. The two cross-section measurement channels: - Fiducial analysis considers events with a candidate jet with pT > 450 GeV. The signal strength corresponds to events within a fiducial volume which include ggF+VBF+VH+ttH produced events with pT(H) > 450 GeV and |yH| < 2. - Differential analysis considers events within four bins of candidate jet pT 250-450 GeV, 450-650 GeV, 650-1000 GeV, > 1 TeV. The four signal strengths correspond to events within STXS-like volumes which include ggF+VBF+VH+ttH produced events with |yH| < 2 that are in of the the four pT(H) ranges 300-450 GeV, 450-650 GeV, 650-1000 GeV, and > 1 TeV.
