摘要：

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) over bar (s) mu(+)mu(-)). Constraints on right handed insertions, in particular, improve considerably in the large tan regime where the contributions to Bs mixing are dominated by double Higgs penguins. Similarly, the allowed regions of parameter space when varying multiple insertions also decrease significantly. (c) 2006 Elsevier B.V. All rights reserved.
