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

Abstract

Higgs boson production cross-sections in proton–proton collisions are measured in the <i>H→WW^∗→eνμν</i> decay channel. The proton–proton collision data were produced at the Large Hadron Collider at a centre-of-mass energy of 13 TeV and recorded by the ATLAS detector in 2015 and 2016, corresponding to an integrated luminosity of 36.1 fb⁻¹. The product of the <i>H→WW^∗</i> 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</sub>−1.7</sub>(syst.) pb and 0.50^+0.24_−0.22(stat.) ± 0.17(syst.) pb, respectively, in agreement with Standard Model predictions.
