Uncertainty study of Ds^-(D^-)→γlv^-(1=e,μ) decays determined by wave function
Abstract
Wave function is important for determining decay constants fDs^- and fD^-. Using the 5 types of D meson wave functions in the heavy quark limit, we studied the uncertainties of radiative pure-leptonic decays of Ds^-(D^-) mesons. The branching ratios are (
