J/φ强子衰变过程的角分布螺旋度形式

HELICITY FORMALISM OF THE ANGULAR DISTRIBUTION FOR THE J/ψ HADRONIC DECAY PROCESS

本文给出了e^+e^-→J/φ→V+X,V→P_1P_2和e^+e^-→J/φ→V+X,X→P_4P_5过程的角分布螺旋度形式.为e^+e^-实验数据分析提供了理论公式.

In this paper we give the helicity formalism of the angular distribution for processes e^+e^-→J/φ→V+X, V→P_1P_2 and e^+e^-→J/φ→V+X, X→P_4P_5. It provides the theoretical formula for e^+e^- experimental data analysis.
