摘要：

The current wealth of charmless B decay data may suggest the presence of final state rescattering. In a factorized amplitude approach, better fits are found by incorporating two SU(3) rescattering phase differences, giving delta similar to 65degrees and sigma similar to 90degrees -100degrees. Fitting with unitarity phase phi(3) as a fit parameter gives phi(3) similar to 96degrees, the CP asymmetries A(pipi), S-pipi agree better with BaBar, and the sigma phase is slightly lower. Keeping phi(3) = 60degrees fixed in fit gives S-pipi similar to -0.9, which agrees better with Belle. With the sizable delta, sigma rescattering phases as fitted, many direct CP asymmetries flip sign, and B-0 --> pi(0)pi(0), K-K+ rates are of order 10(-6), which can be tested soon.
