  • Heavy quark symmetry predicts the value of B→D and B→D∗ transition matrix elements of the current cγμ(1 − γ5)b, at zero recoil (where in the rest frame of the B the D or D∗ is also at rest). We use chiral perturbation theory to compute the leading corrections to these predictions which are generated at low momentum, below the chiral symmetry breaking scale.
