AbstractAbstract
[en] We discuss the theoretical uncertainties attendant to the determination of |Vcd|/|Vcs| from semileptonic D decay. Four different theoretical approaches are considered. Currently, agreement at the level of a factor of 2 for the various theoretical approaches exists so that, indeed, precise experimental data -- such as precise lepton energy spectra and decay width data -- would discriminate among the models considered. 8 refs., 1 fig
