Description
We show how an accidental U(1) Peccei-Quinn (PQ) symmetry can arise in a realistic Pati-Salam unified theory of flavour. A QCD axion arises from a linear combination of A4 triplet favons, which are responsible for fermion flavour structures and thus specific flavour-violating couplings of the axion are predicted. We also discuss the prospect of probing such a flavourful axion in future experiments.
