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 Jx of the boson resonance X and the helicity amplitude ratios of the process J/ψ→V+X.
