Abstract：
The process e⁺e^-→J/ψ→γ+X(J^Pc),X→BB (baryon and anti-baryon) is analyzed by using the helicity angular distribution method. The angular and the projection angular distribution formulas for different spin-parity of the resonance X are obtained. With these formulas, we can determine the spin of the resonance X through the analysis of the experimental data.
- spin parity ,
- resonance ,
- angular distribution ,
- helicity amplitude
