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

D. Delepine, J. -M. Gerard, J. Pestieau +1

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 $δ\approx…
