摘要：

A number of B meson decays may proceed only through participation of the spectator quark, whether through amplitudes proportional to f(B)/m(B) or via rescattering from other less-suppressed amplitudes. An expected hierarchy of amplitudes in the absence of rescattering will be violated by rescattering corrections. Such violations could point the way toward channels in which final-state interactions could be important. Cases in which final state-phases can lead to large CP asymmetries are pointed out.
