Özet
A search for a massless dark photon ?? is conducted using 4.5 fb-1 of e+e- collision data collected at center-of-mass energies between 4.600 and 4.699 GeV with the BESIII detector at BEPCII. No significant signal is observed, and the upper limit on the branching fraction B(?c+?p??) is determined to be 8.0×10-5 at 90% confidence level. © 2022 authors.
