Domain walls in strongly coupled theories
Abstract
Domain walls in strongly coupled gauge theories are discussed. A general mechanism is suggested automatically leading to massless gauge bosons localized on the wall. In one of the models considered, outside the wall the theory is in the nonAbelian confining phase, while inside the wall it is in the Abelian Coulomb phase. The confining property of the nonAbelian theories is a key ingredient of the mechanism which may be of practical use in the context of the dynamic compactification scenarios. In supersymmetric (N = 1) YangMills theories the energy density of the wall can be exactly calculated in the strong coupling regime. This calculatioin presents a further example of nontrivial physical quantities that can be found exactly by exploiting specific properties of supersymmetry. A key observation is the fact that the wall in this theory is a BPSsaturated state.
