Measurement of the form factors in the decay D+ →ωe+νe and search for the decay D+ →φe+νe
(American Physical Society, 2015-10-19)
Using 2.92fb-1 of electron-positron annihilation data collected at a center-of-mass energy of s=3.773GeV 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. ...
