Event details

Abstract: Since the discovery of a boson - consistent with the Standard Model Higgs boson - in 2012 it has been observed in many of its predicted production and decay channels. However the most probable decay of the Higgs boson to a pair of bottom quarks, which has a branching ratio of 58%, remained elusive during Run 1 of the Large Hadron Collider. This talk presents the observation of H->bb decays and VH production, which were recently obtained by the ATLAS experiment. The focus is the presentation of the analysis targeting associated production with a vector boson, V(H->bb), which provides the largest sensitivity for the probed decay and production mode. This analysis uses 79.8 fb-1 of proton-proton collision data, which were collected in Run 2 of the Large Hadron Collider at a centre-of-mass energy of 13 TeV.
