Abstract
Using the decay modes D*+ --> D+ pi0 and D*0 --> D0pi0, we have measured the D*+-D+ and D*0-D0 mass differences to be 140.64 +/- 0.08 +/- 0.06 and 142.12 +/- 0.05 +/- 0.05 MeV, respectively. Combining these measurements with the Particle Data Group average for the D*+-D0 mass difference, we obtain isospin mass splittings for D*+-D*0 and D+-D0 of 3.32 +/- 0.08 +/- 0.05 and 4.80 +/- 0.10 +/- 0.06 MeV. We discuss the implications of these measurements for models of isopsin mass differences and model-dependent estimates of f(D).
