越来越多的证据表明,QCD(以及一般的四维规范理论)具有一种隐藏的对称性,这种对称性并不表现为经典拉格朗日的对称性,而是只在量子水平上被揭示出来。在这篇综述中,我们考虑的标度依赖的局域规范不变的运营商和高能量(Regge)行为的散射振幅来解释,在这两种情况下的有效QCD动力学描述的完全可积系统,证明是相关的著名的海森堡自旋链及其推广。
There is a growing amount of evidence that QCD (and four-dimensional gauge theories in general) possesses a hidden symmetry which does not exhibit itself as a symmetry of classical Lagrangians but is only revealed on the quantum level. In this review we consider the scale dependence of local gauge invariant operators and high-energy (Regge) behavior of scattering amplitudes to explain that the effective QCD dynamics in both cases is described by completely integrable systems that prove to be related to the celebrated Heisenberg spin chain and its generalizations.
