Resumen:
A measurement of the Higgs boson production cross sections via associated WH and ZH production using H→WW∗→ℓνℓν decays, where ℓ stands for either an electron or a muon, is presented. Results for combined WH and ZH production 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 36.1 fb−1 recorded at a centre-of-mass energy of 13 TeV. The products of the H→WW∗ branching fraction times the WH and ZH cross 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.
