Abstract

Using a data sample of 1.31×109 J/ψ events accumulated with the BESIII detector, the decay J/ψ→ppφ is studied via two decay modes, φ→KS0KL0 and φ→K+K-. The branching fraction of J/ψ→pp φ is measured to be B(J/ψ→pp φ)=[5.23±0.06(stat)±0.33(syst)]×10-5, which agrees well with a previously published measurement, but with a significantly improved precision. No evident enhancement near the pp-mass threshold, denoted as X(pp ), is observed, and the upper limit on the branching fraction of J/ψ→X(pp )φ→pp φ is determined to be B(J/ψ→X(pp )φ→pp φ)<2.1×10-7 at the 90% confidence level.
