Abstract
The Higgs boson properties has been measured at the ATLAS experiment since its discovery, obtaining a good agreement with the Standard Model predictions. Evidence of H → b¯b is crucial for constraining the overall Higgs boson decay width and to confirm the Yukawa coupling to quark sector. The most promising production mode is the V H, where the Higgs boson is in association with a vector boson. The vector boson decaying into leptons helps in the extraction of the signal from the multijet background which dominates the H → b¯b. One of the main sources of background for the Standard Model V H(H → b¯b) search is the production of V (V = W or Z) bosons in the association with jets. This contribution describes the ATLAS simulation setup used to model this irriducible background in proton-proton collisions at centre-of-mass energy of 13 TeV. Several Monte Carlo generators are studied in different phase-space regions and compared to unfolded data distribution, with additional requirements on the heavy-flavour content of the associated jets.
