Updated Constraints from B Physics on the MSSM and the NMSSM

Understand

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.
