Final State Interaction Phases in $B\to K\pi$ Decay Amplitudes

Abstract

A simple Regge pole model for $K\pi$ scattering explains the large $e^{i\delta }$ between isospin amplitudes which is observed at the D meson mass ($\delta \approx \pi /2$). It predicts $\delta \approx 14^{\circ }-20^{\circ }$ at the B mass. Implications for ($B\to K\pi$) decays and extensions of the model to other two-body decay channels are briefly discussed.
