Searching for New Physics in Non-Leptonic B Decays

Abstract

We present allowed regions in the space of observables of certain non-leptonic B-meson decays that characterize these modes within the Standard Model. A future measurement of observables lying significantly outside of these regions would indicate the presence of new physics. Making use of SU(3) arguments, we give the range for $B\to \pi K$ decays, and for the system of $B_d\to {\pi }^{+}{\pi }^{-}$, $B_s\to K^{+}{K}^{-}$ modes.
