论文摘要
我们重新访问具有过渡磁矩的重型中性钩子（中性元素）的模型，以解释Miniboone $4.8σ$过量的电子样事件。我们进行了详细的基于蒙特卡洛的分析，以重新检查模型参数空间中的首选区域，以解释小酮，考虑到由于EV规模的无菌中微子而引起的振荡可能贡献。然后，我们使用来自密涅瓦的中微子 - 电子弹性散射数据在模型上得出鲁棒的约束。我们发现Minerva排除了很大的参数空间区域，但允许的解决方案存在于$2σ$的置信度。在此模型中，专用的密涅瓦分析很可能能够探究整个小型酮的偏好区域。
We revisit models of heavy neutral leptons (neutrissimos) with transition magnetic moments as explanations of the $4.8σ$ excess of electron-like events at MiniBooNE. We perform a detailed Monte Carlo-based analysis to re-examine the preferred regions in the model parameter space to explain MiniBooNE, considering also potential contributions from oscillations due to an eV-scale sterile neutrino. We then derive robust constraints on the model using neutrino-electron elastic scattering data from MINERvA. We find that MINERvA rules out a large region of parameter space, but allowed solutions exist at the $2σ$ confidence level. A dedicated MINERvA analysis would likely be able to probe the entire region of preference of MiniBooNE in this model.
