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 $b\bar{b}$ 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 $H\to b\bar{b}$ 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 $H\to b\bar{b}$ decays and reduce the overwhelming multijet background. The result of this analysis using the full 2015 and 2016 dataset, corresponding to $36.1~\text{fb}^{-1}$ of data will be presented, which will be one of the most sensitive searches to date for $H\to b\bar{b}$ decays. |
