Proposal for Higgs and Superpartner Searches at the LHCb Experiment

TL;DR

This paper explores how the LHCb experiment can detect supersymmetric particles, especially neutralinos with displaced vertices, potentially observing the Higgs boson earlier than other detectors in certain scenarios.

Contribution

It proposes a novel search strategy for supersymmetry at LHCb focusing on displaced vertices from neutralino decays, extending sensitivity to squark masses around 1 TeV.

Findings

LHCb can detect squark masses up to ~1 TeV.

LHCb may observe the Higgs boson before ATLAS and CMS in specific decay scenarios.

Displaced vertex signatures are promising for supersymmetry searches.

Abstract

The spectrum of supersymmetric theories with R-parity violation are much more weakly constrained than that of supersymmetric theories with a stable neutralino. We investigate the signatures of supersymmetry at the LHCb experiment in the region of parameter space where the neutralino decay leaves a displaced vertex. We find sensitivity to squark production up to squark masses of order 1 TeV. We note that if the Higgs decays to neutralinos in this scenario, LHCb should see the lightest Higgs boson before ATLAS and CMS.
