论文摘要
我们将轴上的概念概括为扩展的Electroweak仪表对称设置。我们提出了歌手 - 瓦尔 - 施加机（SVS）理论的最小轴承扩展，其中标准模型拟合$ \ mathrm {su（3）_l \ otimes u（1）_x} $，从而实现了Anomaly CALCELLATION中的家庭数量，以及Peccei-Quinn（pQ）的解决方案。中微子质量是由I型Dirac Seesaw机制产生的，该机制被SVS和PQ量表的比例抑制，表明在中等的SVS量表中存在新物理学。与DFSZ轴相比，新型功能包括增强的轴突耦合与光子的耦合，以及改变风味的轴轴耦合到夸克。
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 $\mathrm{SU(3)_L\otimes U(1)_X}$, 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 flavour-changing axion couplings to quarks.
