Sumario:A key outstanding observation is the decay of the Higgs boson to b-quarks, motivating a study into the prospects of this channel in future LHC runs. This proceeding summarises a simulated analysis of Standard Model H->bb decay, produced in association with a vector boson at the ATLAS detector for 14 TeV proton-proton collisions at the high-luminosity LHC. Efficiency and resolution smearing functions were applied to generator-level Monte Carlo samples to reproduce the expected performance of the upgraded ATLAS detector, for the foreseen amount of pile- up due to multiple overlapping proton-proton collisions. The expected signal significance and signal strength is presented for 300/fb and 3000/fb with an average pile-up of 60 and 140 respectively.
