Flavor SU(3) analysis of charmless B->PP decays

Abstract

We perform a global fits to charmless $B\to PP$ decays which independently constrain the $(\bar{\rho },\bar{\eta })$ vertex of the unitarity triangle. The fitted amplitudes and phase are used to predict the branching ratios and CP asymmetries of all decay modes, including those of the $B_s$ system. Different schemes of SU(3) breaking in decay amplitude sizes are analyzed. The possibility of having a new physics contribution to $K\pi$ decays is also discussed.
