• O4; Amplitudes for ψ(2S) sequential decays into 2(π+π-)p(p-)γ via XcJ are constructed in effective coupling scheme. A Mote-Carlo simulation is carried out to study angular distributions of the decayed particles in laboratory system. The results can be taken as a reference for measuring the decay of XcJ into Ξ-Ξ+ at BESII/BEPC in the near future.
