We propose UV-completions of Froggatt–Nielsen–Peccei–Quinn models of fermion masses and mixings with flavored axions, by incorporating heavy fields. Here, the U(1) Froggatt–Nielsen symmetry is identified with the Peccei–Quinn symmetry to solve the strong CP problem along with the mass hierarchies of the Standard Model fermions. We take into account leading order contributions to the fermion mass matrices giving rise to Nearest-Neighbour-Interaction structure in the quark sector and \(A_2\) texture in the neutrino sector. A comprehensive numerical analysis has been performed for the fermion mass matrices. Subsequently, we investigate the resulting axion flavor violating couplings and the axion-photon coupling arising from the model.

我们提出了费米子质量和与风味轴子混合的 Froggatt-Nielsen-Peccei-Quinn 模型的 UV 完成，通过合并重场。在这里，U (1) Froggatt-Nielsen 对称性与 Peccei-Quinn 对称性相结合，以解决强 CP 问题以及标准模型费米子的质量等级。我们考虑了费米子质量矩阵的主要阶次贡献，导致夸克扇区中的最近邻相互作用结构和中微子扇区中的\(A_2\)纹理。对费米子质量矩阵进行了全面的数值分析。随后，我们研究了由此产生的轴子风味违反耦合和模型产生的轴子-光子耦合。
