Domain walls with non-Abelian clouds
Domain walls with non-Abelian clouds
Domain walls in $U(N)$ gauge theories, coupled to Higgs scalar fields with degenerate masses, are shown to possess normalizable non-Abelian Nambu-Goldstone (NG) modes, which we call non-Abelian clouds. We construct the moduli space metric and its K\"ahler potential of the effective field theory on the domain walls by focusing on …
