<i>SO</i>(10) models with flavour symmetries: classification and examples
We establish the full list of flavour symmetry groups which may be enforced, without producing any further accidental symmetry, on the Yukawa-coupling matrices of an SO(10) Grand Unified Theory with arbitrary numbers of scalar multiplets in the 10, 126, and 120 representations of SO(10).For each of the possible discrete non-Abelian …
