Description:
Author(s): J. Yelton et al. (CLEO Collaboration) We report the first observation of the decay D + → η ′ e + ν e in two analyses, which combined provide a branching fraction of B ( D + → η ′ e + ν e )=(2.16±0.53±0.07)×10 -4 . We also provide an improved measurement of B ( D + → η e + ν e )=(11.4±0.9±0.4)×10 -4 , provide the first form factor measurement, and set the improved upper... [Phys. Rev.
