摘要：

We analyze final state strong interaction effects in B --> D rho and B --> D*pi decays using the Regge model. We find that, due to the smallness 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 quarks. Our conclusion is that for B decays into states containing charm, final state interaction effects should play a minor role.
