摘要
本文讨论了J/φ辐射衰变中胶子球候选者θ/f_2(1720)的产生及其衰变.我们发现,为了解释过程J/φ→r+θ的螺旋度振幅之比x和y,除了θ粒子的S波分量之外,必须考虑两个D波分量(ι=2,s=0,2)的贡献.我们还讨论了D’波分量(ι=2,s=2)是否存在的可能的实验检验.
In this paper we discuss the production and decay of the glueball candidate θ/f_2,(1720)in the J/ψ radiative decay.We find that in order to explain the helicity amplitude ratios x and y of the process J/ψ→γ+θ,the contribution of two D wave components(l=2,S=0,2)has to be considered in addition to the S wave component.We also discuss the possible experimental test for the existence of the D'wave component(l=2,S=2).
