Peccei-Quinn, Froggatt-Nielsen, axion, axiflavon, flavourful axion


A model is presented, where the Froggatt-Nielsen and Peccei-Quinn symmetries are identified. This provides a solution to the strong CP problem and an explanation to the fermion mass hierarchy. At leading order, the quark mass matrix possess a Nearest-Neighbour-Interaction structure, while the neutrino mass matrix has a Majorana A2 texture. From a thorough numerical analysis the viability of this model is asserted, by comparing against current measurements. The data obtained from this analysis is then used to study properties from the axion.
