论文摘要
非常成功的标准模型尚未完成。它不能解释宇宙中的重型不对称性，暗物质的存在或中微子的非零质量。提出其他重型中性瘦素（HNL）存在的标准模型的扩展是充分动机的，可以解释其中几种现象。此外，$ \ Mathcal {o}的光无菌中微子（\ text {ev}/c^{2}）$可以解释实验观察到的振荡异常。中微子最小标准模型提出了带有质量$ \ Mathcal {o}（\ text {kev}/c^{2} {2} - \ text {gev}/c^{2}）$的HNL，而更奇特的模型可以预测非常大的质量，直至gut量表。由于假设HNL的大量模型，实验探索的质量范围很大。可以在现有的中微子，梁垃圾场和基于对撞机的实验的现有中微子进行实验搜索，并且取决于签名，可以约束其他中微子与三个活动中微子中的任何一个之间的混合。
The highly successful Standard Model is not complete. It does not explain the baryonic asymmetry in the Universe, the existence of dark matter or the non-zero masses of the neutrinos. Extensions of the Standard Model that propose the existence of additional Heavy Neutral Leptons (HNLs) are well-motivated and can explain several of these phenomena. In addition, light sterile neutrinos of $\mathcal{O}(\text{eV}/c^{2})$ can explain experimentally observed oscillation anomalies. The Neutrino Minimal Standard Model proposes HNLs with masses $\mathcal{O}(\text{keV}/c^{2} - \text{GeV}/c^{2})$, while more exotic models predict very large masses, up to the GUT scale. Due to the multitude of models which hypothesize HNLs, the mass range to be explored by experiments is large. Experimental searches for HNLs can be conducted at existing neutrino, beam dump and collider-based experiments, and, depending on the signature, can constrain mixing between additional neutrinos and any of the three active neutrinos.
