论文摘要
鉴于最近的$ r_ {k^{(*)}} $数据$ b \中的中性风味异常,以k^{(*)} \ ell^+ \ ell^ - $衰减,我们以扩展的331量规论框架进行了定量解释。我们通过添加带有新型331个电荷的两种额外的Lepton物种来实现这一目标,同时确保模型保持无异常。与规范的331型模型相反,第一和第二Lepton家族的仪表指控彼此不同,从而违反了Lepton风味的普遍性。我们通过添加为小型中微子质量提供足够描述所需的中性费米来进一步扩展模型。
In light of the recent $R_{K^{(*)}}$ data on neutral current flavour anomalies in $B \to K^{(*)} \ell^+ \ell^-$ decays, we re-examine their quantitative interpretation in terms of an extended 331 gauge theory framework. We achieve this by adding two extra lepton species with novel 331 charges, while ensuring that the model remains anomaly free. In contrast to the canonical 331 models, the gauge charges of the first and second lepton families differ from each other, allowing lepton flavour universality violation. We further expand the model by adding the neutral fermions required to provide an adequate description for small neutrino masses.
