扩展QCD (XQCD)，由Kaplan提出[D]。B. Kaplan, [j],[14]，是一个具有附加玻色子辅助场的QCD的有趣的重新表述。在保持配分函数与原QCD完全相同的同时，XQCD自然包含了低能强子模型的性质。通过分析二维(X)QCD的重正化群流，了解辅助自由度在低能区扮演什么样的角色以及强子图像是如何出现的。
Extended QCD (XQCD), proposed by Kaplan [D. B. Kaplan, arXiv:1306.5818], is an interesting reformulation of QCD with additional bosonic auxiliary fields. While its partition function is kept exactly the same as that of original QCD, XQCD naturally contains properties of low-energy hadronic models. We analyze the renormalization group flow of 2D (X)QCD, which is solvable in the limit of a large number of colors, to understand what kind of roles the auxiliary degrees of freedom play and how the hadronic picture emerges in the low-energy region.
