New Strategies to Extract $\beta$ and $\gamma$ from $B_{d} \to \pi^{+} \pi^{-}$ and $B_{s} \to K^{+} K^{-}$

The decays $B_d\to \pi^+ \pi^-$ and $B_s\to K^+ K^-$ are related to each other by interchanging all down and strange quarks, i.e. through the $U$-spin flavour symmetry of strong interactions. A completely general parametrization of the CP-violating observables of these modes is presented within the...
