Description

We study the B-parameter (''bag factor'') for mixing within a recently developed heavy-light chiral quark model. Non-factorizable contributions in terms of gluon condensates and chiral corrections are calculated. In addition, we also consider 1/μQ corrections within heavy quark effective field theory. Perturbative QCD effects below μ=mb known from other work are also included. Considering two sets of input parameters, we find that the renormalization invariant B-parameter is B=1.51±0.009 for Bd and B=1.40±0.16 for Bs. (orig.)
