摘要
We report a new measurement of the D∗ branching ratios, using data obtained with the Mark III detector at the e+e− storage ring SPEAR at s=4.14 GeV. A fit to the recoil mass squared spectrum of D mesons reconstructed through the decay modes K−π+π+ and K−π+ is used to extract the D∗+ → γD+, π0D+, π+D0 and D∗0 → γD0, π0D0 branching ratios.
