Description
Following the discovery of the Higgs boson in 2012 by both the ATLAS and CMS experiments, a wealth of papers have been published concerning measurements or observations of the Higgs' decay modes. However, the most dominant decay mode, $H→b\bar{b}$, proved to be an elusive and challenging search due to the low signal-to-background environment, and a diverse range of backgrounds arising from multiple Standard Model processes. The backgrounds include $W$+jets, $Z$+jets, and $t\bar{t}$ production, among others. Measurements of $WH$ and $ZH$ production based on 139 fb$^{-1}$ of 13 TeV $pp$ collisions with the ATLAS detector are presented, with the $W$ or $Z$ boson decaying into charged leptons (electrons or muons, including those produced from the leptonic decay of a tau lepton), in the $H→b\bar{b}$ decay channel. The production of a Higgs boson in association with a $W$ or $Z$ boson has been established with observed (expected) significances of 4.0 (4.1) and 5.3 (5.1) standard deviations, respectively.
