Supersymmetric constraints from Bs -> mu+mu- and B -> K* mu+mu- observables

TL;DR

This paper examines how recent LHCb measurements of Bs -> mu+mu- and B -> K* mu+mu- constrain supersymmetric models, highlighting the importance of these observables in limiting parameter space.

Contribution

It provides a detailed analysis of the impact of recent experimental limits on constrained SUSY scenarios, especially CMSSM and NUHM, considering theoretical uncertainties.

Findings

Recent Bs -> mu+mu- limits strongly restrict large tan(beta) regions.

Angular observables from B -> K* mu+mu- offer additional constraints at moderate tan(beta).

Theoretical predictions are carefully estimated to assess experimental constraints.

Abstract

We study the implications of the recent LHCb limit and results on Bs -> mu+mu- and B -> K* mu+mu- observables in the constrained SUSY scenarios. After discussing the Standard Model predictions and carefully estimating the theoretical errors, we show the constraining power of these observables in CMSSM and NUHM. The latest limit on BR(Bs -> mu+mu-), being very close to the SM prediction, constrains strongly the large tan(beta) regime and we show that the various angular observables from B -> K* mu+mu- decay can provide complementary information in particular for moderate tan(beta) values.
