Abstract
We report the first observation of the decay D+→η ′e+νe in two analyses, which combined provide a branching fraction of B(D+→η ′e+νe)=(2.16±0.53±0.07) ×10-4. We also provide an improved measurement of B(D +→ηe+νe)=(11.4±0.9±0. 4)×10-4, provide the first form factor measurement, and set the improved upper limit B(D+→e+νe)<0. 9×10-4 (90%C.L.).
