FINAL-STATE INTERACTIONS IN B-]D-RHO AND B-]D-ASTERISK-PI DECAYS

We analyze final state strong interaction effects in B --> D rho and B --> Dpi decays using the Regge model. We find that, due to the small ness of the contributions from the non-leading Regge trajectories (rho , f, pi etc.), final state interaction phases are small if the Pomeron coupling to the charm quark is suppressed in comparison to lighter qu arks. Our conclusion is that for B decays into states containing charm , final state interaction effects should play a minor role.
