Description
Summary:The parton and hadron cascade model {\footnotesize PACIAE} is employed to confirm the BESIII newest observation of glueball-like particle \(\rm X(2370)\) production in \(e^+e^-\) collisions at \(\sqrt{s}=4.95\,\mathrm{GeV}\). We coalesce the \(\rm X(2370)\) glueball state with two gluons in the simulated partonic final state by the Dynamically Constrained Phase-space Coalescence ({\footnotesize DCPC}) model. Alternative configuration of \(\rm X(2370)\) molecular state is recombined in the simulated hadronic final state with \(\pi^{+},\pi^{-},K^{+}, K^{-},K_{S}^{0},K_{S}^{0}\) and \(\eta'\) by {\footnotesize DCPC} model. The resulted particle transverse momentum spectrum and rapidity distribution, etc. show a significant discrepancy between the two states. They are not only serving as criteria to distinguish the \(\rm X(2370)\) glueball state or molecular state, but also confirming the BESIII observation of glueball-like particle \(\rm X(2370)\) productions in \(e^+e^-\) collisions.
