N"非汉字符号"束缚态问题的研究

A Study of N ■ Bound State

从夸克 反夸克通过介子场耦合的模型出发研究了 (N Ω )LST是否存在束缚态的问题 .计算表明当考虑了u s(d s)湮灭K 为介子的机制后 ,(N Ω)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 quark-antiquark and the meson fields are included. A resonating group method (RGM) calculation shows that (N)_(0212)could be a bound state with considerably large binding energy, when the mechanism of u(d) annihilation to K~* is considered.
