Description
The form factors of the D→K*eν are calculated by means of the QCD sum rules method for the three-point correlators. The decay width is obtained. Theoretical evaluation for the ratio of the decay rates into the channels D→K*eν and D→Keν (the last decay was explored in this approach by T.M. Aliev, V.L. Eletsky, and Ya.I. Kogan) is compared with the experimental values. There is an agreement with the experimental data within the theoretical and experimental uncertanties involved. 14 refs
