The mu-from-nu SSM can reproduce the measured B_s^0 -> mu+ mu- branching ratio while also satisfying the Bbar -> X_s gamma constraint, for certain ranges of At, kappa, upsilon_nu^c, and A_lambda.

abstract
We update constraints from B physics observables on the parameters of the MSSM and the NMSSM, combining them with LEP constraints. Presently available SM and Susy radiative corrections are included in the calculations, which will be made public in the form of a Fortran code. Results for the tan(beta) and M_{H^+} dependence of b -> s gamma are presented, as well as constraints on the NMSSM specific case of a light CP odd Higgs scalar. We find that the latter are essentially due to B_s -> mu^+ mu^-, but they do not exclude this possibility.

$B_s^0 \rightarrow \mu^+ \mu^-$ in a flavor violating extension of MSSM
The mu-from-nu SSM can reproduce the measured B_s^0 -> mu+ mu- branching ratio while also satisfying the Bbar -> X_s gamma constraint, for certain ranges of At, kappa, upsilon_nu^c, and A_lambda.
