More about quark Yukawa textures from selection rules without group actions

Tatsuo Kobayashi, Yume Nishioka, Hajime Otsuka +1

We study the coupling selection rules associated with non-group symmetries, i.e., ${\mathbb{Z}}_2$ gauging of ${\mathbb{Z}}_M$ symmetries. We clarify which Yukawa textures can be deriv…
