| dc.description.abstract | Using a data sample of 1.31 × 10⁹ J/ψ events accumulated with the BESIII detector, the decay J/ψ → pp̅φ is studied via two decay modes, φ → K_S⁰K_L⁰ and φ → K⁺K⁻. The branching fraction of J/ψ → pp̅φ is measured to be ℬ(J/ψ → pp̅φ) = [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 pp̅ mass threshold, denoted as X(pp̅), is observed, and the upper limit on the branching fraction of J/ψ → X(pp̅)φ → pp̅φ is determined to be ℬ(J/ψ → X(pp̅)φ → pp̅φ) < 2.1 × 10⁻⁷ at the 90% confidence level. | en_US |
