Abstract
The measurements of the Higgs boson decays to fermions allow to test the Yukawa couplings and to understand the mass generation of fermions. In the Standard Model, the H → b¯b decay is the dominating decay with a branching ratio of 58%, although its observation is experimentally challenging at LHC because of the large multijet background. The search for the H → b¯b decay is therefore performed exploiting the associated production of a Higgs boson with a W or a Z boson (V = W/Z), whose leptonic decays make the signature of these processes easier to identify. This paper describes the search for the V H(→ b¯b) process using pp collisions data taken by ATLAS at LHC at 13 TeV and presents the first observation of the Higgs coupling to b-quarks. Differential cross section of the V H(→ b¯b) production at 13 TeV are also presented.
