Studying High Energy Final State Interactions by N/D Method

Abstract

We discuss the final state interaction effects at high energies via a multi-channel N/D method. We find that the 2 by 2 charge--exchange final state interactions typically contribute an enhancement factor of a few times $10^{-2}$ in the $B$ meson decay amplitudes, both for the real and the imaginary part. We also make some discussions on the elastic rescattering effects.
