The decay Bs -> mu+ mu-: updated SUSY constraints and prospects

TL;DR

This paper assesses how recent experimental limits on the decay Bs -> mu+ mu- constrain supersymmetric models, highlighting that these constraints can surpass direct searches and discussing future detection prospects at the LHC.

Contribution

It provides updated SUSY constraints based on latest decay measurements and introduces a double ratio method to enhance these constraints.

Findings

Constraints can be stronger than direct SUSY searches in some scenarios.

Double ratio of leptonic decays improves constraint strength.

Potential for observing Bs -> mu+ mu- at LHC during 7 TeV run.

Abstract

We perform a study of the impact of the recently released limits on BR(Bs -> mu+ mu-) by LHCb and CMS on several SUSY models. We show that the obtained constraints can be superior to those which are derived from direct searches for SUSY particles in some scenarios, and the use of a double ratio of purely leptonic decays involving Bs -> mu+ mu- can further strengthen such constraints. We also discuss the experimental sensitivity and prospects for observation of Bs -> mu+ mu- during the sqrt(s)=7 TeV run of the LHC, and its potential implications.
