摘要：

Heavy quark effective theory can be used to study the semileptonic B-(*)-->D-(*) decays in the limit that the heavy quark masses are infinite. We calculate the lowest order chiral corrections, which are of O(1/M-2), from the breaking of heavy quark symmetry at the zero recoil point in quenched chiral perturbation theory. These results will aid in the extrapolation of quenched lattice calculations from the light quark masses used on the lattice down to the physical ones.
