Description
We study the hadronic and radiative decays of D/sup asterisk+/ and D/sup asterisk0/. Using SU(4) symmetry for the hadronic decays, we convert the branching ratios into total rates for D/sup asterisk+/ and D/sup asterisk0/. We point out a potential problem with the ratio GAMMA(D/sup asterisk+/→D+π0)/GAMMA(D/sup asterisk+/→D 0π+). Finally, using the measured branching ratios for radiative decays, we extract the ''experimental'' radiative rates. We find these radiative rates puzzling as they are difficult to understand in an SU(4) or broken-SU(4) scheme
