摘要：

We analyse the decay D+ --> K*0BAR e + v(e) in view of the new experimental data. We find that the experimental central value of the decay amplitude A2 is incompatible with QCD sum rules, whereas the large value of the vector coupling is reproduced unambiguously. The ratios come out very stable to be A2/A1 = 1.2 +/- 0.2, V/A1 = 2.2 +/- 0.2.
