Helicity amplitude analysis of J/ψ and ψ(2S)→Ξ(1530)Ξ¯(1530)

We perform a helicity amplitude analysis for the processes of e+e−→J/ψ,ψ(2S)→Ξ(1530)Ξ¯(1530)→ππΞΞ¯→4πΛΛ¯→6πpp¯. The joint angular distribution for these processes are obtained, which allows a proper estimation of the detection efficiency using helicity amplitude information. In addition, the sensitivities of measurement of hyperon asymmetry decay parameters for these processes are discussed.
