Measurement of the associated production of the Higgs boson with a vector boson in 13 TeV pp collisions with the ATLAS detector

After the Higgs discovery at LHC in 2012, most of ATLAS analyses are focusing the attention on precision measurements of Higgs kinematic properties and on the search of new decay modes sensitive to physics Beyond the Standard Model. One of the most interesting channels is the Higgs boson decay into two b-quarks due to the large branching ratio (58%). The best sensitivity is presently obtained by studying the associated Higgs boson production with a vector boson V (V = W or Z) decaying leptonically. The same dataset has been re-interpreted in the Simplified Template Cross Section framework. This framework facilitates the measurement of the differential pp → V H cross section used to extract information on the Higgs couplings and to put limits on Beyond the Standard Model effects. In this paper an overview of the most recent results on the observation of V H production and H → b¯b decay mode will be presented, together with the measurements of the V H, H → b¯b production as a function of the vector boson transverse momentum.
