Abstract
Various rescattering sources are analyzed in the context of the SU(3) flavor symmetry. In particular, the possibility to account for intermediate charm at the hadronic level in B to PP is thoroughly investigated. Then, the rescattering sources are compared in light of recent decay measurements of B to two charmless pseudoscalars, with emphasis on the size of strong phases and on patterns of direct CP-asymmetries.
