Description
The processes e+ + e-→J/ψ→γ + X, X→pp-bar are discussed using the generalized moment analysis method. The moment expressions of the above processes are given. And they are used to determine the spin of the resonance X decaying to pp-bar. The helicity amplitude radios of the above processes in terms of moment expressions are also given
