Vacuum replicas in two-dimensional QCD
arXiv:hep-ph/0308273 · doi:10.1016/j.physletb.2003.08.059
Abstract
Two-dimensional QCD is studied from the point of view of existence of multiple chirally noninvariant solutions to the mass-gap equation. The ground-state solution is reproduced and an infinite set of replica solutions is discovered for this equation using the WKB quantisation procedure.
