Study of $J\mathrm{/}\psi \to p\bar{p}\varphi$ at BESIII

Using a data sample of $1.31\times {10}^9$ $J\mathrm{/}\psi$ events accumulated with the BESIII detector, the decay $J\mathrm{/}\psi \to p\bar{p}\varphi$ is studied via two decay modes, $\varphi \to K_S^0{K}_L^0$ and $\varphi \to K^{+}{K}^{-}$. The branching fraction of $J\mathrm{/}\psi \to p\bar{p}\varphi$ is measured to be $$\mathcal{B}$(J/\psi\to p\bar{p}\phi)=[5.23\pm0.06(\mbox{stat})\pm0.33(\mbox{syst})]\times10^{-5}$, which agrees well with a previously published measurement, but with a significantly improved precision. No evident enhancement near the $p\bar{p}$ mass threshold, denoted as $X(p\bar{p})$, is observed, and the upper limit on the branching fraction of $J\mathrm{/}\psi \to X(p\bar{p})\varphi \to p\bar{p}\varphi$ is determined to be $$\mathcal{B}$(J/\psi\to X(p\bar{p})\phi\to p\bar{p}\phi)<2.1\times10^{-7}$ at the 90% confidence level.
