论文摘要
重中性瘦素（HNL）构成了几种中微子质量产生机制的基础。实验搜索取决于它们与主动中微子的质量和混合，而在大多数情况下，质量和混合的排除区域都取决于两个假设：$（i）$存在$ $ hnl的存在，其中$（ii）$ comply仅与$ $ $ $ lepton的风味相比，$（ii）$混合。在这项工作中，我们讨论了如何重新解释对撞机搜索的限制，从而放松了这些假设，提供了一个简单的配方来重塑具有通用混合模式的模型中的界限，其中至少两个HNL与活动扇形耦合。
Heavy neutral leptons (HNL) constitute the building blocks of several neutrino mass generation mechanisms. Experimental searches depend on their masses and mixings with the active neutrinos, and exclusion regions in the plane of mass and mixing rely most of the time on two assumptions: $(i)$ the existence of $one$ HNL, which $(ii)$ mixes dominantly with only $one$ lepton flavor. In this work we discuss how to reinterpret the limits from collider searches relaxing these assumptions, providing a simple recipe to recast the bounds in models with generic mixing patterns, and in which at least two HNLs are coupled to the active sector.
