Abstract

The formfactors of the semileptonic decays B->{rho}e{nu}, D->{rho}e{nu} are calculated with help of the QCD sum rules method for the three-point correlators. The estimates of the decay widths are represented. From the experimental limits for Br(B{sup -}{rho}{sup 0}e{sup -}{nu}-bar) the upper limits on the element V{sub bu} of the Kobayashi-Maskawa matrix are obtained. These limits are more strict as compared with the limits being suggested in other papers. 15 refs.
