在非交换规范理论的协变正则形式的框架下，证明了在ca（x）Ta μ（x）cc（x）和fabcAbμ（x）cc（x）中存在束缚态，色禁闭的突出问题就有可能得到解决，其中ca，Ta μ和Aaμ分别代表Faddeev-Popov鬼、夸克和胶子.在存在这样的束缚态时，不管它们的质量值如何，理论的规范不变性（BRS不变性）自动确保夸克和胶子的渐近场通过范数抵消机制与物理扇区解耦。
In the framework of the covariant canonical formulation of nonabelian gauge theories, it is shown that the outstanding problem of color confinement may be solved if one proves the existence of bound states in the channels of ca(x)TaΨ(x) and fabcAbμ(x)cc(x), where the fields ca, Ψ and Aaμstand for the Faddeev-Popov ghost, the quark and the gluon, respectively. In the presence of such bound states, irrespectively of their mass values, the gauge invariance (BRS invariance) of the theory automatically ensures that the asymptotic fields of the quark and the gluon decouple from the physical sector by a norm-cancellation mechanism.
