A Study of N Bound State
-
摘要: 从夸克反夸克通过介子场耦合的模型出发研究了(N)LST是否存在束缚态的问题. 计算表明当考虑了u(d)湮灭K*为介子的机制后, (N)LST是有可能形成结合能较大的束缚态. The structures of (N)LST systems are studied in the SU(3)quark model, in which the coupling between quarkantiquark and the meson fields are included. A resonating group method (RGM) calculation shows that (N)0212could be a bound state with considerably large binding energy, when the mechanism of u(d) annihilation to K* is considered.Abstract: The structures of (N)LST systems are studied in the SU(3)quark model, in which the coupling between quarkantiquark and the meson fields are included.
