Domain Walls in Large N Supersymmetric QCD
We explicitly construct BPS domain walls interpolating between neighboring chirally asymmetric vacua in the large N limit of pure supersymmetric QCD. The BPS equations for the corresponding ZN symmetric order parameter effective Lagrangian reduce to those in the AN Landau-Ginsburg model assuming that the higher derivative terms in the Kähler potential are suppressed in the large N limit. These ...
متن کاملCounting Domain Walls in N = 1 Super
We study the multiplicity of BPS domain walls in N =1 super Yang-Mills, by maximally Higgsing the theory with fundamental matter. The number of domain walls connecting two specified vacuum states is then determined via the Witten index of the induced worldvolume theory. This theory is a sigma model with a Grassmanian target space which arises as the coset associated with the global symmetries b...
متن کاملStatic Domain Walls in N = 1 Supergravity
We study supersymmetric domain walls in N=1 supergravity theories, including those with modular-invariant superpotentials arising in superstring compactifications. Such domain walls are shown to saturate the Bogomol’nyi bound of wall energy per unit area. We find static and reflection asymmetric domain wall solutions of the self-duality equations for the metric and the matter fields. Our result...
متن کاملDomain Walls and Decay Rate of the Excited Vacua in the Large N Yang-Mills Theory
In the (non-supersymmetric) Yang-Mills theory in the large N limit there exists an infinite set of non-degenerate “vacua”. The distinct vacua are separated by domain walls whose tension determines the decay rate of the false vacua. I discuss the phenomenon from a field-theoretic point of view, starting from supersymmetric gluodynamics and then breaking supersymmetry by introducing a gluino mass...
متن کاملVortex configurations in the large N limit
We study the properties of vortex-like configurations which are solutions of the SU(N) Yang-Mills classical equations of motion. We show that these solutions are concentrated along a two-dimensional wall with size growing with the number of colors. PACS: 11.15.-q, 11.15.Ha
