Axion quality from the (anti)symmetric of SU( N $$ \mathcal{N} $$ )
Abstract We propose two models where a U(1) Peccei-Quinn global symmetry arises accidentally and is respected up to high-dimensional operators, so that the axion solution to the strong CP problem is successful even in the presence of Planck-suppressed operators. One model is SU( N $$ \mathcal{N} $$...
