Abstract:
The hadronic decay process J/ψ→V1+X,X→V2+V3,V2,V3→2P(or 3P)(here Vi and P stand for vector and pseudoscalar meson,respectively) has been discussed in this paper.For the intermediate state X with various spin-parity JP,the corresponding helicity formalism of angular distribution formulas have been presented.They are helpful for determining the spin-parity of the intermediate state in above process by using the J/ψ events obtained from BEPC.
