The LHCb has recently published the observation of $B_s \rightarrow \mu^+ \mu^-$ with a branching ratio that agrees with the Standard Model (SM). There are many blog posts about it (See: Of Particular Significance). The result initiated a debate over its implication on Supersymmetry in general, which I don't want to discuss here. But it certainly affects some Supersymmetric models that may have a different prediction than that of the SM.
My questions are,
- Which models in particular are affected (or variants of models)? What is the MSSM status? The NMSSM?
- Does the result affect some of the parameter space of a particular model, or does it rule out an entire model/or variant of a model?
