Higgs boson production cross-sections in proton–proton collisions are measured in the H→WW ⁎→eνμν 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 36.1fb −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 −1.1 +1.2(stat.) −1.7 +1.8(syst.)pb and 0.50 −0.22 +0.24(stat.)±0.17(syst.)pb, respectively, in agreement with Standard Model predictions.
