两Skyrmion间的集团效应

Intermediate Range Attraction of NN Interaction from Clustering Effect in Skyrme Model

当两个skyrmion重叠时,可产生一种类分子的束缚力,这可能是核子间相互作用中中程吸引的来源之一。研究证实此吸引力足够强,可使两核子形成束缚态,似乎不再需要唯象地引进未曾观测到的标量介子。

As two skyrmions overlap, a molecular-like binding may arise. This may be one of the main sources of missing intermediate range attraction in NN interaction. The attraction is found to be strong enough to form bound state of two n.ucleons. It seems then that one no longer needs to introduce phenomenologically scalar meson which has never been Observed.
