Jul 2, 2018 at 23:39 comment added Mitchell Porter There are already models where color SU(3) is actually the diagonal subgroup of two separately gauged SU(3)s, but I never saw this chiral segregation before.
Jul 2, 2018 at 20:24 comment added Mitchell Porter Weird idea! The strong gauge group would be SU(3)L x SU(3)R, with chiral quarks also still interacting via Higgs yukawa terms.
