| 英文摘要 | We study the light quark dependence of the Isgur-Wise function for B-a-->D-a and B-a-->D-a* in the framework of QCD sum rules. At zero recoil, all the Isgur-Wise functions are equal, as required by heavy quark symmetry, and at nonzero recoil the Isgur-Wise function for B, decay falls faster than that for B-u,B-d decay, which is just contrary to the recent prediction of the heavy meson chiral perturbation theory. As a by-product we also estimate SU(3)-breaking effects in the mass and the decay constant. |
