Measurements of the production cross-sections of a Higgs boson in association with a vector boson and decaying into WW* with the ATLAS detector at s = 13 TeV
| Resumo: | Measurements of the total and differential Higgs boson production cross-sections, via W H and ZH associated production using H \(\rightarrow\) WW\(*\) \(\rightarrow\) \(\ell\nu\ell\nu\) and H \(\rightarrow\) WW\(*\) \(\rightarrow\) \(\ell\nu jj\) decays, are presented. The analysis uses proton-proton events delivered by the Large Hadron Collider at a centre-of-mass energy of 13 TeV and recorded by the ATLAS detector between 2015 and 2018. The data correspond to an integrated luminosity of 140 fb\(^{-1}\). The sum of the W H and ZH cross-sections times the H \(\rightarrow\) WW\(*\) branching fraction is measured to be \( 0.44^{+0.10}_{-0.09} \) (stat.) \( ^{+0.06}_{-0.05} \) (syst.) pb, in agreement with the Standard Model prediction. Higgs boson production is further characterised through measurements of the differential cross-section as a function of the transverse momentum of the vector boson and in the framework of Simplified Template Cross-Sections. |
