Observation of the radiative decay D*+-> D+gamma
We have observed a signal for the decay D*+ → D+ γ at a significance of 4 standard 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...
