Description
The widths for decays Dsup(*)->Dγ and Dsup(*)->Dπ are obtained from QCD sum rules in external vector and axial fields. The branching ratios are shown to be in a reasonable agreement with the existing experimental data. The total widths are two orders of magnitude less than the experimental upper limit. As a byproduct we get the residue of Dsup(*) into vector current. (orig.)
