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=13 TeV with the ATLAS detector

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+1.2_−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.
