Abstract: (arXiv)

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 decays and allows to derive constraints on NP contributions to penguin amplitudes or on the

B_s

mixing phase. We illustrate these capabilities with a simplified analysis using the recent measurements by the LHCb Collaboration, neglecting correlations with other SM observables.
