B-decays and B- antiB mixing within a heavy-light chiral quark model

Abstract

We describe a recently developed heavy-light chiral quark model and show how it can be used to calculate decay amplitudes for heavy mesons. In particular, we discuss B- antiB mixing, B -> D antiD, B -> D eta' and the beta term for D* -> D gamma .
