Searching For Boosted \( H \rightarrow b \bar{b} \) at the LHC

Abstract

In this paper, we create a "boosted" VHbb analysis to search for events where the Higgs boson has high transverse momentum, and its daughter b quarks can be contained inside an anti-kt jet with radius R\(_{0}\)= 0.8, by defining preselections and training a boosted decision tree. By analyzing the 1-lepton channel, we reclaim VHbb events that were previously unidentified, and also uncover an overlap with the original VHbb analysis. By treating this overlap and its complements as separate analysis categories, we predict a 5% gain in VHbb observational significance using our 1-lepton channel results, not accounting for systematic errors.
