论文摘要
作为一种颜色限制机制，到目前为止，已经通过各种方式讨论了由于QCD涉及的亚伯单孔引起的双重Meissner效应。但是仍然存在一个尚未解决的重要问题。它是方案的规范不变性，或者换句话说，是通过阿贝尔双重Meissner效应来解释非阿贝尔颜色限制的原因。在此表明，基于违反非阿贝尔比安奇身份（VNABI）的随机阿贝尔方法可以证明SU（3）不变性，并解释为什么仅凭颜色单独的颜色可以在QCD的限制阶段中生存，而在阿贝尔人双重Meissner效应的框架内，由于阿贝尔双重莫斯纳（Abelian Dual Meissner）效应。这与hooft的阿贝尔投影方案完全不同，后者引入了额外的部分量规或Bonati等人的想法。这也基于vnabi。 Bonati等。假设vnabi与't Hooft Tensor有关，并且关系可以证明“ T Hooft的Abelian投影计划”的规格不变性。但是最后一个想法是不正确的。 vnabi和't Hooft张量之间的关系的存在无法解释hooft的Abelian投射方案的规格不变性。
As a color confinement mechanism, a dual Meissner effect due to Abelian monopoles involved in QCD has been discussed so far in various ways. But still there is an important problem unsolved. It is gauge invariance of the schemes or, in other words, the reason why non-Abelian color confinement is explained by means of the Abelian dual Meissner effect. Here it is shown that a random Abelian method based on the violation of non-Abelian Bianchi identity (VNABI) could prove SU(3) invariance and explain why color-singlets alone can survive in the confinement phase of QCD in the framework of the Abelian dual Meissner effect due to Abelian monopole condensation. This is completely different from the 't Hooft's Abelian projection scheme which introduces an additional partial gauge-fixing or the idea of Bonati et al. which is based also on VNABI. Bonati et al. say that VNABI is related to the 't Hooft tensor and the relation can prove the gauge invariance of the 't Hooft's Abelian projection schemes. But the last idea is found to be incorrect. Existence of the relation between VNABI and the 't Hooft tensor alone can not account for gauge invariance of 't Hooft's Abelian projection schemes.
