论文摘要
我们报告了最新的理解颜色限制$ qCD $的进展，为真空的双重电导率。构造了单极的创建操作员的规格不变版本，其真空期望值是顺序参数。该顺序参数是从头开始的量规不变的，没有红外差异，在狭窄的相位是有限的，在脱合相的相位中消失了。自然的解释也出现了为什么通量管中的电场线对冷凝单极的颜色取向不记忆。进一步的副产品是可以用铬电场的两点真空平行相关器进行订单参数。
We report on recent progress in understanding confinement of colour in $QCD$ as dual superconductivity of the vacuum. A gauge invariant version of the creation operator of monopoles is constructed whose vacuum expectation value is the order parameter. This order parameter is gauge-invariant from scratch, has no infrared divergences, is finite in the confined phase and vanishes in the deconfined phase. A natural explanation also emerges of why the electric field lines in the flux tubes keep no memory of the colour orientation of the condensing monopoles. A further by-product is that the order parameter can be traded with the two-point vacuum parallel correlator of the chromo-electric field.
