Measurements of gluon–gluon fusion and vector-boson fusion Higgs boson production cross-sections in the H → WW⁎ → eνμν decay channel in pp collisions at √s=13TeV with the ATLAS detector

Abstract

Higgs boson production cross-sections in proton–proton collisions are measured in the H→WW∗→eνμνdecay channel. The proton–proton collision data were produced at the Large Hadron Collider at a centre-of-mass energy of 13TeVand recorded by the ATLAS detector in 2015 and 2016, corresponding to an integrated luminosity of 36.1fb−1. The product of the H→WW∗branching fraction times the gluon–gluon fusion and vector-boson fusion cross-sections are measured to be 11.4+1.2−1.1(stat.)+1.8−1.7(syst.)pband 0.50+0.24−0.22(stat.) ±0.17(syst.)pb, respectively, in agreement with Standard Model predictions.
