Abstract：
This paper presents the helicity formalism of the angular distribution for the cascade decay processes e ⁺+ e ^-→ J/ψ → V + X,X → P ₁+ Y,Y → P ₂+ P ₃(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.
