Constraints on Higgs boson production with large transverse momentum using H → b ¯ b decays in the ATLAS detector

Journal article

This paper reports constraints on Higgs boson production with transverse momentum above 1 TeV. The analyzed data from proton–proton collisions at a center-of-mass energy of 13 TeV were recorded with the ATLAS detector at the Large Hadron Collider from 2015 to 2018 and correspond to an integrated luminosity of 136     fb − 1 . Higgs bosons decaying into b ¯ b are reconstructed as single large-radius jets recoiling against a hadronic system and are identified by the experimental signature of two b -hadron decays. The experimental techniques are validated in the same kinematic regime using the Z → b ¯ b process. The 95% confidence-level upper limit on the cross section for Higgs boson production with transverse momentum above 450 GeV is 115 fb, and above 1 TeV it is 9.6 fb. The Standard Model cross section predictions for a Higgs boson with a mass of 125 GeV in the same kinematic regions are 18.4 fb and 0.13 fb, respectively.
