Evidence for the Higgs boson decay to a bottom quark-antiquark pair

Evidence for the standard model Higgs boson decay to a bottom quark-antiquark pair is presented. The search for the $H \rightarrow b\overline{b}$ decay was performed for the following processes where the Higgs boson is produced in association with an electroweak vector boson: $Z(\nu\nu)H$, $W(\mu\nu)H$, $W(e\nu)H$, $Z(\mu\mu)H$, $Z(ee)H$. The analyzed data was recorded by the CMS experiment at the LHC during Run 2 in 2016, and corresponds to an integrated luminosity of $35.9 \textrm{ fb}^{-1}$ at $\sqrt{s} = 13 \textrm{ TeV}$. An excess of events is observed in data with a significance of 3.3 standard deviations and a signal strength of $1.2 \pm 0.4$ relative to the SM Higgs boson production. The combnation of these results with the similar Run 1 analysis yields a significance of 3.8 standard deviations and a signal strength of $1.06 \pm 0.3$.
