正如Witten在M理论的基础上提出的,QCD弦可以终止于域壁上。我们在N=1超对称QCD中Polyakov环和胶子凝聚的有效场论框架下给出了这一效应的解释。在高温相变过程中,不同胶子凝结物的封闭相的畴壁被一层限定相完全湿润。因此,即使在低温下,波利亚科夫环在畴壁上也具有不消失的期望值。因此,在靠近壁面的地方,静态夸克的自由能是有限的,从它发出的弦可以在壁面上结束。{版权所有}{ital 1998} {ital美国物理学会
As argued by Witten on the basis of M theory, QCD strings can end on domain walls. We present an explanation of this effect in the framework of effective field theories for the Polyakov loop and the gluino condensate in N=1 supersymmetric QCD. The domain walls separating confined phases with different values of the gluino condensate are completely wet by a layer of deconfined phase at the high-temperature phase transition. As a consequence, even at low temperatures, the Polyakov loop has a nonvanishing expectation value on the domain wall. Thus, close to the wall, the free energy of a static quark is finite and the string emanating from it can end on the wall. {copyright} {ital 1998} {ital The American Physical Society}
