摘要
从单胶子交换正反夸克对产生模型出发,计算了N-N相互作用中方盒图的等效两介子交换势,它随γ的变化关系与唯象σ介子交换势随γ的变化关系的趋势是一致的.
The effective two-meson-exchange potential with regard to the box diagram in the N-N interaction has been derived by virtue of the one-gluon-exchange quark-antiquark pair creation model. The result shows that the general feature of this effective potential agrees with that of the phenomenological σ-meson exchange potential in coordinate space.
