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