A measurement of the Higgs boson production cross sections via associated WHand ZHproduction using H→WW∗→ ν νdecays, where stands for either an electron or a muon, is presented. Results for combined WHand ZHproduction are also presented. The analysis uses events produced in proton–proton collisions collected with the ATLAS detector at the Large Hadron Collider in 2015 and 2016. The data correspond to an integrated luminosity of 36.1fb−1recorded at a centre-of-mass energy of 13TeV. The products of the H→WW∗branching fraction times the WHand ZHcross sections are measured to be 0.67+0.31−0.27(stat.)+0.18−0.14(syst.)pb and 0.54+0.31−0.24(stat.)+0.15−0.07(syst.)pb respectively, in agreement with the Standard Model predictions
