Abstract
These proceedings present the performance and calibration of the X→bb¯ tagger, developed by the ATLAS experiment to identify boosted Higgs bosons decaying in the dominant decay channel to a beauty quark-antiquark pair. Data-MC scale factors for the signal efficiency are calculated using Zγ and Z+jets events, in four regions of pT, and vary between 1.45+0.47−0.45 and 0.55+0.23−0.22, whilst the mis-tag efficiency scale factors are measured using single-lepton tt¯ events, also in four regions of pT, and vary between 1.1±0.12 and 1.0±0.16. The modelling of the large-\textit{R} jet kinematics is evaluated using multijet events enriched in g→bb¯ splitting, achieved by requiring a non-isolated muon contained inside the large-\textit{R} jet.
