Testing the Standard Model and searching for New Physics with $B_d\to \pi \pi$ and $B_s\to KK$ decays

M. Ciuchini, E. Franco, S. Mishima +1

We propose to perform a combined analysis of $B\to \pi \pi$ and $B_s\to K^{+}{K}^{-}$ modes, in the framework of a global CKM fit. The method optimizes the constraining power of these deca…
