Abstract:
In the context of M-theory, Witten has argued that an intriguing phenomenon occurs, namely that QCD strings can end on domain walls. We present a simpler explanation of this effect using effective field theory to describe the behavior of the Polyakov loop and the gluino condensate in N = 1 supersymmetric QCD. We describe how domain walls separating distinct confined phases appear in this effective theory and how these interfaces are completely wet by a film of deconfined phase at the high-temperature phase transition. This gives the Polyakov loop a non-zero expectation value on the domain wall. Consequently, a static test quark which is close to the interface has a finite free energy and the string emanating from it can end on the wall.Note:
