description | Measurements of Higgs boson decays to fermions are important to understand the mass generation of fermions. In the Standard Model, the $H\rightarrow b\bar{b}$ decay is expected to account for almost 60\% of the Higgs branching fraction, but experimentally it is difficult to observe because of overwhelming backgrounds from Standard Model processes. For this reason, the search for the $H\rightarrow b\bar{b}$ decay is performed exploiting the more distinct signature of Higgs boson production in association with a leptonically decaying vector boson (V). This paper describes the search for the VH($\rightarrow b\bar{b}$) process using pp collision data taken at 13 TeV, and presents also the results from the combination with the search for $H\rightarrow b\bar{b}$ using other production processes and center-of-mass energies, leading to the observation of the $H\rightarrow b\bar{b}$ decay. |
