Özet
The singly Cabibbo suppressed decay ?c+?p?? is measured 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. Evidence for ?c+?p?? with a statistical significance of 3.6? is reported with a double-Tag approach. The ?c+?p?? absolute branching fraction is determined to be (5.62-2.04+2.46±0.26)×10-4, where the first and second uncertainties are statistical and systematic, respectively. Our result is consistent with the branching fraction obtained by the Belle collaboration within the uncertainty of 1?.
