Description

$\rm b\bar{b}$-pairs are the largest decay mode of a 125 GeV SM Higgs boson, with a branching fraction of 58%. As a consequence, studying $\rm H \to b\bar{b}$ has great importance to constrain the total Higgs boson decay width. In order to suppress overwhelming irreducible background from QCD multijet production of b quarks, $\rm H \to b\bar{b}$ decays are searched for at hadron colliders in events in which the production of the Higgs boson is associated with a heavy boson (W or Z) decaying leptonically. Nonetheless, it has been proposed to use events where the Higgs boson is produced in association with a high-$\rm p_{T}$ jet, achieving high sensitivity for highly boosted b-tagged jets from the Higgs decay. In this presentation the latest ATLAS results will be shown about the search for 13 TeV events with $\rm H \to b\bar{b}$ decays associated with a high-$\rm p_{T}$ jet.
