Final State Interactions in $B->D\rho$ and $B->D^{\ast }\pi$ Decays

Abstract

We analyze final state strong interaction effects in $B->D\rho$ and $B->D^{\ast }\pi$ 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.
