论文摘要
MiniBoone的最新更新加强了观察到的$4.8σ$超过$ e $的事件。由此和其他显着的与标准模型预测（例如Muon $（g-2）$）偏离的偏差，我们通过黑暗中微子领域提出了一种解决低能异常的解决方案。该模型是可重新分配的，还可以解释带有无异常和深色$ u（1）^\ prime $ $ $级对称对称性的轻中微子质量。大型动力学混合会导致在$ e^+e^ - $ colliders以S渠道产生沉重的中性瘦素，我们指出并解释了Babar Monophoton数据中观察到的$ \ gtrsim2σ$多余的。我们的模型还与旧加速器实验中看到的异常$ e $ $ $ $ $兼容，以及在CCFR上观察到的双顶点特征过多。
A recent update from MiniBooNE has strengthened the observed $4.8σ$ excess of $e$-like events. Motivated by this and other notable deviations from standard model predictions, such as the muon $(g-2)$, we propose a solution to low energy anomalies through a dark neutrino sector. The model is renormalizable and can also explain light neutrino masses with an anomaly-free and dark $U(1)^\prime$ gauge symmetry broken at the GeV scale. Large kinetic mixing leads to s-channel production of heavy neutral leptons at $e^+e^-$ colliders, where we point out and explain a $\gtrsim 2σ$ excess observed in the BaBar monophoton data. Our model is also compatible with anomalous $e$-like events seen at old accelerator experiments, as well as with an excess of double vertex signatures observed at CCFR.
