Measurements of gluon–gluon fusion and vector-boson fusion Higgs boson production cross-sections in the H?WW*?e?µ? decay channel in pp collisions at vs=13TeV with the ATLAS detector

Higgs boson production cross-sections in proton–proton collisions are measured in the H?WW*?e?µ? decay 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.)pb and 0.50+0.24-0.22(stat.) ±0.17(syst.)pb, respectively, in agreement with Standard Model predictions.
