Abstract
We study the final-state interactions in decays
through
processes where
the inelastic rescattering occurs via single pion exchange.
The next-to-leading order low-energy effective Hamiltonian and
Bauer-Stech-Wirbel (BSW)
model are used to evaluate the weak transition matrix elements
and final-state interactions. We found that the final-state
interaction effects in
processes are significant. The Fleischer-Mannel relation for
the Cabibbo-Kobayashi-Maskawa (CKM) angle
can be significantly
modified.
