The stability of non-Abelian $A_4$ vortices in $SO(3)$ gauge theory

Yoshihiko Abe, Tetsutaro Higaki, Kazuya Murakami +2

We study the linear energetic stability of non-Abelian vortices in an $SO(3)$ gauge-Higgs theory with residual gauge group $A_4$. In our previous work, we identified two families o…
