Measurement of B(J/psi -> eta ' e(+)e(-)) and search for a dark photon
(2019)
Using a data sample of (1310.6 +/- 7.0) x 10(6) J/psi decay events collected with the BESIII detector at BEPCII, we study the electromagnetic Dalitz decay J/psi -> eta ' e(+)e(-) with two dominant eta' decay modes, eta' ...
