Observation of Higgs in $b\bar{b}$ channel from ATLAS and CMS

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 overwh...

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.
