Abstract

In the present paper, the dual symmetries of dense quark matter phase diagram found in some massless three- and two-color NJL models in the mean field approximation have been shown to exist at a more fundamental level as dual transformations of fields and chemical potentials leaving the Lagrangian invariant. As a result, the corresponding dual symmetries of the full phase diagram can be shown without any approximation. And it has been shown not only in the NJL models, but also in framework of two- and three-color massless QCD itself. This is quite interesting, since one might say that it is not very common to show something completely non-perturbatively in QCD.

密集同位素和手征不对称 QCD 的双重对称性

本文证明了在均值场近似中的一些无质量三色和双色 NJL 模型中发现的致密夸克物质相图的对偶对称性在更基本的层次上是作为场和化学势的对偶变换而存在的，并使拉格朗日不变。因此，全相图的相应对偶对称性无需任何近似即可显示。不仅在 NJL 模型中，而且在双色和三色无质量 QCD 本身的框架中也得到了证明。这是非常有趣的，因为可以说，在 QCD 中完全以非微扰方式展示某些东西并不常见。
