J/φ强子衰变过程的矩分析

THE MOMENT ANALYSIS FOR THE J/ψ HADRONIC DECAY PROCESS

本文给出了过程e^++e^-→J/ψ→V+X,V→P_1P_2或P_1P_2P_3和X→PP的角分布螺旋度形式,并在此基础上进行了矩分析,得到了若干关系式,有助于确定玻色共振态X的自旋J_x以及过程J/ψ→V+X的螺旋度振幅之比.

In this paper we give the helicity formalism of the angular distribution for process e^++ e^-→J/ψ→>V + X, V→P_1P_2 or P_1P_2P_3 and X→PP simultaneously. By using this formalism the moment analysis and some relations have been obtained, which is helpful in determining the spin J_x of the boson resonance X and the helicity amplitude ratios of the process J/ψ→V+X.
