摘要:

研究了标量共振f0(1370),f0(1500)和f0(1710)在J/psi强辐射三体衰变中的作用,其中J/psi衰变为V + PP(gamma gamma),J/psi衰变为gamma + PP(VV),P(V)表示赝标(矢量)介子.我们假设标量的结果从胶球夸克偶素混合计划,而过渡过程的动力学描述在一个有效的手征拉格朗日方法。目前的J/psi到V + P P的数据是很好地再现,辐射过程的预测作为进一步的测试这种情况。

英文摘要:

We study the role of the scalar resonances f0(1370), f0(1500) and f0(1710) in the strong and radiative three-body decays of J/psi with J/psi to V + P P (gamma gamma) and J/psi to gamma + P P (V V), where P (V) denotes a pseudoscalar (vector) meson. We assume that the scalars result from a glueball-quarkonium mixing scheme while the dynamics of the transition process is described in an effective chiral Lagrangian approach. Present data on J/psi to V + P P are well reproduced, predictions for the radiative processes serve as further tests of this scenario.
