Abstract
Using a 281pb-1 data sample collected at the ψ(3770) resonance with the CLEO-c detector at the Cornell Electron Storage Ring, we report the first observation of D+→ηe+νe. We also set upper limits for D+→η′e+νe and D+→φe+νe that are about 2 orders of magnitude more restrictive than those obtained by previous experiments. © 2009 The American Physical Society.
