J/ψ三级二体强衰变过程的自旋-宇称分析

Spin and parity analysis for the three-step two-body hadronic decay processes of J/ψ

本文给出了级联衰变过程e^++e^-→J/φ→V+X,X→P_1+Y,Y→P_2+P_3(V代表矢量介子,P_i代表赝标介子)的角分布螺旋度形式,为通过J/φ三级二体强衰变过程对中间态X粒子进行自旋-宇称分析提供理论公式。

The helicity formalism of the angular distribution for the cascade decay process e^+ + e^-→J/φ→V+X,X→P_1+Y,Y→P_2+P_3 (V represents a vector meson and P_i(i=1,2,3) are the pseudoscalar mesons) is presented in this paper. It provides the theoretical formulas for the spin-parity analysis of the intermediate state X through a three-step two-body hadronic decay processes of J/φ.
