摘要：

We show that existing data on the semileptonic decays DKe+e and DK*e+e provide information on matrix elements relevant for the rare B»-meson decays B»Ke+e-, B»K*e+e-, and B»K* and that future data on B»e»e and B»e»e will further constrain them. A discussion of how the form factors for these latter decays are in turn determined by semileptonic D decays at the corresponding recoil momenta is also presented. © 1990 The American Physical Society.
