Description
Since the Higgs boson discovery in 2012, the main interest in the domain of Higgs physics has now shifted to determining the parameters of the Higgs sector in order to probe potential contributions from physics beyond the Standard Model. The decay channel to b-quark jets plays a crucial role in this program, because of its dominant contribution to the total Higgs boson decay width, but it is very challenging to observe because of the large backgrounds. Establishing the search for this decay mode at the LHC has required significant advances in multiple experimental tools, especially in the domains of b-jet tagging and multivariate analysis techniques. I will illustrate the contributions of these advancements to the final ATLAS results from Run-I of the LHC and discuss the prospects and challenges ahead for Run-2.
