Measurement of the form factors in the decay D+ → ωe+νe and search for the decay D+→ϕe+νe

Using 2.92  fb−1 of electron-positron annihilation data collected at a center-of-mass energy of s√=3.773  GeV with the BESIII detector, we present an improved measurement of the branching fraction B(D+→ωe+νe)=(1.63±0.11±0.08)×10−3. The parameters defining the corresponding hadronic form factor ratio...
