Abstract

Higgs boson production cross-sections in proton–proton collisions are measured in the $H \to W W^{⁎} \to e ν μ ν$ 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 $H \to W W^{⁎}$ 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 ${0.50}_{- 0.22}^{+ 0.24} (stat .) \pm 0.17 (syst .) pb$ , respectively, in agreement with Standard Model predictions.
