Studies of D^+ -> {eta', eta, phi} e^+ nu_e

Studies of D^+ -> {eta', eta, phi} e^+ nu_e

We report the first observation of the decay D^+ -> eta' e^+ nu_e in two analyses, which combined provide a branching fraction of B(D+ -> eta' e nu) = (2.16 +/- 0.53 +/- 0.07) x 10^{-4}. We also provide an improved measurement of B(D+ -> eta e nu) = (11.4 +/- 0.9 +/- 0...
