Final-State Interactions in Nonleptonic Weak Decays of D and B Mesons

Abstract

We study final-state interactions in nonleptonic weak decays in statistical models by averaging over ensembles of strong interaction S-matrices. The models range from one with completely random strong interactions, which gives extensive mixing between physical states, to models with feeble final-state interactions, characterized by small phase shifts.
