Extension of the Buchalla-Safir bound

Abstract

I provide a simple derivation of the Buchalla-Safir bound on gamma. I generalize it to the case where an upper bound on the phase of the penguin pollution is assumed. I apply the Buchalla-Safir bound, and its generalization, to the recent Belle data on CP violation in B --> pi+ pi-.
