Abstract：
In this paper we give the helicity formalism of the angular distribution for process e⁺+e^－→J/ψ→V+X,V→P₁P₂ or P₁P₂P₃ and X→pp simultaneously.By using this formalism the moment analysis and some relations have been obtained,which is helpful in determining the spin J_x of the boson resonance X and the helicity amplitude ratios of the process J/ψ→V+X.
