Detecting Higgs bosons in the bb̄ decay channel using forward proton tagging at the LHC

Research output: Contribution to journalArticle

Abstract

A detailed study is presented of the search for Higgs bosons in the b channel in the central exclusive production process at the LHC. We present results for proton tagging detectors at both 220m and 420m around ATLAS or CMS. We consider two benchmark scenarios; a Standard Model (SM) Higgs boson and the m h max scenario of the Minimal Supersymmetric Standard Model (MSSM). Detector acceptance, smearing and event trigger strategies are considered. We find that the SM Higgs will be challenging to observe in the b channel without improvements to the currently proposed experimental configuration, but a neutral scalar MSSM Higgs Boson could be observable in the b channel with a significance of 3σ or greater within three years of data taking at all luminosities between 2 × 10 33 cm -2 s -1 and 10 34 cm -2 s -1, and at 5σ or greater after three years in certain scenarios. © SISSA 2007.
