Abstract

We study B _s →μ ⁺ μ ⁻ in the context of the R-parity violating minimal supergravity in the high-tan β regime. We find that the lowest value of the branching ratio can go well below the present LHCb sensitivity and hence B _s →μ ⁺ μ ⁻ can even be invisible to the LHC. We also find that the present upper bound on Br (B _s →μ ⁺ μ ⁻) puts strong constraint on the minimal supergravity parameter space. The constraints become more severe if the upper bound is close to its standard model prediction.
