摘要
把轻赝标介子之间的矢量介子交换模型推广到了Ds K系统,推导了单交换所对应的相互作用势.在此基础上对Ds K系统可能存在的束缚态进行了理论研究,计算了束缚能随截断因子的变化和相对应的波函数.结果说明:Ds K系统会形成束缚态或者D0*(2400)±可能含有Ds K分子态的组分.
We explore the generalization of the vector mesons exchange model of two light pseudoscalar mesons. A potential of DsK system from one Ф exchange is derived. Based on the potential, the possible bound-states of DsK system are studied, the binding energy and wave function of the bound-state are calcu- lated with the cut-off parameter. The results suggest that DsK could form a bound-state or Do . （2400）± may contain the component of DsK molecule.
