Final state interactions in B -> Dρ and B -> D*π decays

We analyze final state strong interaction effects in B -> Dρ and B -> D^*π decays using the Regge model. We find that, due to the smallness of the contributions from the non-leading Regge trajectories (ρ, f, π 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.
