Standard Model Higgs boson production in the decay mode H?bb¯ in association with a W or Z boson for High Luminosity LHC Running

Abstract

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 where the Higgs boson is 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 an integrated luminosity of 300 fb-1 and 3000 fb-1 with an average number of pile-up collisions of 60 and 140 respectively.
