摘要：
We perform a global fits to charmless B -> PP decays which independently constrain the ((rho)over-bar, (eta)over-bar)vertex of the unitarity triangle. The fitted amplitudes and phase are used to predict the branching ratios and CP asymmetries of all decaymodes, 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.
