Abstract
Many searches for Higgs bosons decaying to b quark pairs benefit from the increased Run II centre-of-mass energy by exploiting the boosted kinematic regime at large transverse momenta of the Higgs boson, where the two b-jets are merged into one large radius ($R$) jet. ATLAS uses a boosted $H \rightarrow b\bar{b}$ tagger algorithm to separate Higgs signal from background processes (QCD, W and Z bosons, top quarks). The tagger takes as input a large $R=1.0$ jet with calibrated pseudorapidity, energy and mass scale. It employs b-tagging, Higgs candidate mass, and substructure information. The performance of several operating points in Higgs boson signal, QCD, and $t\bar{t}$ all-hadronic backgrounds are presented. Systematic uncertainties are evaluated so that this tagger can be used in analyses.
