Abstract
CP asymmetry in some exclusive decays of charged B meson are calculate d in a Bethe-Salpeter approach. Hadronic final state interactions are ignored. Complex decay amplitudes are assumed to arise entirely from p erturbative quark-antiquark loops. Calculations are done both with and without the gluon quark-antiquark vacuum polarization loops. The effe cts of neglecting the imaginary parts arising from the diagonal quark- antiquark loops are also studied. (C) 1997 Published by Elsevier Scien ce B.V.
