Abstract

We have observed a signal for the decay D*+→D+γ deviations. From the measured branching ratio B(D*+→D+γ)/B(D*+→D+π0)=0.055±0.014±0.010 we find B(D*+→D+γ) =0.017±0.004±0.003, where the first uncertainty is statistical and the second is systematic. We also report the highest precision determination of the remaining D*+ branching fractions.
