Angular Distributions Analysis for the Hadronic Decay Process
- Received Date: 1991-01-04
Abstract: The hadronic decay processes J/ψ→V1+X、X→ V2 + V3,V2,V3→2P (or 3P) (where Vi and P stand for the vector arid pseudoscalar meson, respectively) are discussed in this paper. For the intermediate state X with various spin-parity JP, the corresponding helicity formalism of the angular distributions are presented. They are helpful for determining the spin-parity of the intermediate state in the above processes by using the J/ψ events
