Abstract

We study the coupling selection rules associated with non-group symmetries, i.e., ℤ2 gauging of ℤM symmetries. We clarify which Yukawa textures can be derived by our selection rules for M=3, 4, and 5, and obtain various textures including the the nearest neighbor interaction type and its extension. Some of them cannot be realized by a conventional group-like symmetry. They lead to interesting phenomenology such as a solution to the strong CP problem without axion.
