Abstract

Upper limits for the decay widths of the D^*+ and D^*0 mesons have been measured using data from e⁺e^- annihilations at √s=29 GeV obtained with the High Resolution Spectrometer at PEP. We find Γ_{D^*+ < 1.1 MeV/c²} at 90% CL from an analysis of the mass difference distribution for the decay mode D^*+→D⁰π⁺. The D^*+-D⁰ mass difference is also measured to be ((45.40±0.05±0.10) MeV/c². We determine Γ_D^*0<2.1 MeV/c²at 90% CL for a D^*0mass of 2007.2 MeV/c², from a search for the decay mode D^*0→D⁺π^- which could occur if the width were sufficiently large.
