Title
B-decays and B- B-bar mixing within a Heavy Light Chiral Quark Model
Abstract
I will present a heavy-light chiral quark model which will be used to estimate low energy effects in terms of soft gluon emission and chiral loops for B- Bbar mixing and some B-meson decays. The soft gluon emission is parametrized by the gluon condensate with the lowest dimension. We obtain a B-hat parameter for B- Bbar mixing in agreement with recent lattice results.
