论文摘要
除少数例外，重型中性瘦素上的大量可用实验界限 - HNL-已依赖于存在仅与一种Lepton风味混合的单个（通常是Majora）无菌效率状态的假设。但是，涉及无菌费米的标准模型的大多数扩展预测了几种HNL的存在，并具有复杂的混合模式。因此，在将HNL的大多数实验范围用于应用于通用情况之前。在这项工作中，我们专注于对重中性瘦素的LHC搜索，并讨论如何考虑与单个HNL的情况下考虑混合的混合时如何重新解释可用的界限，并且在涉及更重的中性lept子的情况下。在后一种情况下，我们还考虑了干扰效应的可能性，并显示了如何重新铸造参数空间的边界。
With very few exceptions, the large amount of available experimental bounds on heavy neutral leptons - HNL - have been derived relying on the assumption of the existence of a single (usually Majorana) sterile fermion state that mixes with only one lepton flavour. However, most of the extensions of the Standard Model involving sterile fermions predict the existence of several HNLs, with complex mixing patterns to all flavours. Consequently, most of the experimental bounds for HNLs need to be recast before being applied to a generic scenario. In this work, we focus on LHC searches of heavy neutral leptons and discuss how to reinterpret the available bounds when it comes to consider mixings to all active flavours, not only in the case with a single HNL, but also in the case when more heavy neutral leptons are involved. In the latter case, we also consider the possibility of interference effects and show how the bounds on the parameter space should be recast.
