Abstract：
This paper presents the helicity formalism of the angular distribution for the cascade decay processes e⁺ + e^- → J/ψ → V + X,X → P₁ + Y,Y → P₂ + P₃ (V represents a vector meson and P_i(i=1,2,3) are the pseudoscalar mesons). It provides the theoretical formulas for the spin-parity analysis of the intermediate state X through a three-step two-body hadronic decay processes of J/ψ.
