Abstract We generalize the idea of the axion to an extended electroweak gauge symmetry setup. We propose a minimal axion extension of the Singer-Valle-Schechter (SVS) theory, in which the standard model fits in SU ( 3 ) L ⊗ U ( 1 ) X , the number of families results from anomaly cancellation, and the Peccei-Quinn (PQ) solution to the strong-CP problem is implemented. Neutrino masses arise from a type-I Dirac seesaw mechanism, suppressed by the ratio of SVS and PQ scales, suggesting the existence of new physics at a moderate SVS scale. Novel features include an enhanced axion coupling to photons when compared to the DFSZ axion, as well as flavor-changing axion couplings to quarks.

摘要 我们将轴子的概念推广到扩展的电弱规范对称设置。我们提出了 Singer-Valle-Schechter (SVS) 理论的最小轴子扩展，其中标准模型适合 SU ( 3 ) L ⊗ U ( 1 ) X ，异常消除导致的家庭数量，以及 Peccei-实现了强 CP 问题的 Quinn (PQ) 解决方案。中微子质量来自 I 型狄拉克跷跷板机制，受 SVS 和 PQ 尺度的比率抑制，表明存在中等 SVS 尺度的新物理学。新特性包括与 DFSZ 轴子相比增强的轴子耦合到光子，以及与夸克的风味改变轴子耦合。
