J/ψ→ωf_2(1270)衰变过程极化结构的研究

Study of the Polarization of J/Ψ→ωf_2(1270) Decay Process

本文用推广的矩分析法研究了过程J/→ωf_2(1270),f_2(1270)→ππ的极化结构,给出了用矩关系式表示的过程的四个螺旋度振幅之比。

In this paper we investigate the polarization structure of the process J/Ψ→ωf_2(1270) and f_2 (1270)→ππ by using the generalized moment analysis method and give some relations of moments to represent four helicity amplitude ratios of the process.
