Accidental SO(10) axion from gauged flavour
Abstract An accidental U(1) Peccei-Quinn (PQ) symmetry automatically arises in a class of SO(10) unified theories upon gauging the SU(3) f flavour group. The PQ symmetry is protected by the ℤ4 × ℤ3 center of SO(10) × SU(3) f up to effective operators of canonical dimension six. However, high-scale c...
