TL;DR

This paper proposes a jet substructure analysis method to improve the search for a light Higgs boson decaying into b-quarks in WH and ZH channels at the LHC, especially at high transverse momentum.

Contribution

It introduces a subjet analysis technique that enhances the detection prospects of a light Higgs in challenging decay channels at high p_t.

Findings

Improved Higgs search sensitivity at high p_t

Potential to recover the H→bb channel as a promising search mode

Enhanced analysis techniques for jet substructure

Abstract

It is widely believed that searching for a light Higgs boson (with a mass around 120 GeV) in the WH and ZH channels, where H decays into $b\bar{b}$, will be very challenging at the LHC. These proceedings describe how this channel can be recovered as a promising search channel at high $p_t$ by using a subjet analysis procedure.
