原子核内的夸克效应

QUARK EFFECTS IN NUCLEI

这篇评述文章说明了下面四个问题:(i)任何色单态夸克反夸克系统的隐色道一定可以用通常的强子道表示出来,因此任何与隐色道有关的物理总可以用通常的强子自由度来解释;(ii)夸克胶子交换和矢量介子交换产生的重子重子自旋轨道耦合力非常相似,因此不能指望用超核的自旋轨道劈裂来区别夸克胶子交换模型和矢量介子交换模型;(iii)对于破坏电荷独立及电荷对称的重子互作用,电磁作用和夸克质量差同样重要,任何电荷相关互作用的计算必须同时考虑电磁作用和夸克质量差;(iV)和QED中的电子脱局域效应相似,我们猜测对QCD可能有夸克脱囚禁效应并且研究了此效应在双重子系统中的表现。

It is shown in this review that: (i) the hidden colour channels of any colour singlet quark-antiquark system can always be expressed in terms of the usual hadronic channels, any physics related to the hidden colour channel can always be explained in terms of the hadronic degree of freedom only; (ii) the spin-orbit forces between baryons resulted from quark-gluon exchange and vector meson exchange are quite similar, therefore it is impossible to distinguish the quark-gluon exchange model from the vector meson exchange model by means of the hyper nuclei spin-orbit splitting; (iii) for the charge independent and symmetry broken interaction between baryons, the electro-magnetic effects are as important as those due to quark mass differences, any charge dependent interactions calculation should take both the electro-magnetic and guark mass difference effects into account; (iv) similar to the electron delocalization effects far QED, we conjectured possible existance of the quark deconfincment effects for QCD and studied its manifestations in the dibaryon systems.
