Description
During Run-1 of the Large Hadron Collider, a particle consistent with the Standard Model Higgs boson was observed coupling directly to the leptonic and bosonic sectors of the Standard Model. The decay of the Standard Model Higgs to bbbar is the most commonly occurring decay mode, with a branching fraction of approximately 58%. Probing this decay is vital to furthering our understanding of the Standard Model. Due to the large multijet background, the direct observation of H → bbbar in the gluon fusion channel is very challenging. Instead, looking for the associated production of a Higgs with a vector boson (W/Z), and triggering on leptonic decays of the vector boson provides an effective way to trigger on the H → bbar decays and reduce the overwhelming multijet background. The latest results of this analysis will be presented, which provides one of the most sensitive searches for H → bbbar decays.
