Abstract:

Most Higgs bosons are expected to decay to a pair of b-quarks, with the Standard Model predicting a branching fraction of about 58%. Probing this decay is important to furthering our understanding of the Higgs sector, but its observation at hadron colliders is complicated by overwhelming Standard Model backgrounds. In this seminar, the search for the Higgs to bb decay, looking at the associated production of the Higgs boson with a W or Z boson, is presented, based on 36 fb-1 of 13 TeV LHC Run 2 data.
