Abstract: | Using a data sample of 1.31 x 10(9) J/Psi events accumulated with the BESIII detector, the decay J/Psi -> p (p) over bar phi is studied via two decay modes, phi -> (KSKL0)-K-0 and phi -> K+K-. The branching fraction of J/Psi -> p (p) over bar phi is measured to be B(J/Psi -> p (p) over bar phi) = [5.23 +/- 0.06(stat) +/- 0.33(syst)] x 10(- 5), which agrees well with a previously published measurement, but with a significantly improved precision. No evident enhancement near the p (p) over bar mass threshold, denoted as X(p (p) over bar), is observed, and the upper limit on the branching fraction of J/Psi -> X(p (p) over bar)phi -> p (p) over bar phi is determined to be B(J/Psi -> X(p (p) over bar)phi -> p (p) over bar phi) < 2.1 x 10(- 7) at the 90% confidence level. |
