Abstract

A recent measurement of the total D+D^{*+} width, Γtot(D+)=(83.3±1.3±1.4)\Gamma_{\rm tot}(D^{*+}) = (83.3 \pm 1.3 \pm 1.4) keV, is shown to be close to earlier predictions based on the single-quark-transition hypothesis. Those predictions are updated using more recent masses and branching fractions to a value of 80.4 keV, with a small uncertainty associated with the radiative branching fractions of D0D^{*0} and D+D^{*+}. A prediction for the total width of D2(2460)D_2(2460) and its partial width into DπD^* \pi and DπD \pi is also updated, and found to be in agreement with experiment.
