Abstract

We discuss the implications, for general flavour mixing, of the recent results regarding the new allowed range for mixing in the B_s meson system, as well as the new improved bounds on BR(B_s→μ⁺μ^-). Constraints on right handed insertions, in particular, improve considerably in the large \tanb regime where the contributions to B_s mixing are dominated by double Higgs penguins. Similarly, the allowed regions of parameter space when varying multiple insertions also decrease significantly.
