论文摘要
LHC的合作通常使用同符号Di-Lepton和JET Signature搜索LHC的合作，而LHC的合作通常会搜索Lepton数字违规（LNV）。在本文中，我们讨论了在中微子质量产生的某些循环模型中，可以通过实验有趣的速率引起的LNV的多级信号。有趣的是，在这样的模型中，观察到的活性中微子质量的较小性，以及最终状态的高多重性，在此类模型的可行参数空间的很大一部分中导致了长期寿命的带电粒子的预测，这些颗粒在检测器中留下了高度电离的轨道。我们专注于此类中一种特定的1环中微子质量模型，并详细讨论其LHC现象学。
Lepton number violation (LNV) is usually searched for by the LHC collaborations using the same-sign di-lepton plus jet signature. In this paper we discuss multi-lepton signals of LNV that can arise with experimentally interesting rates in certain loop models of neutrino mass generation. Interestingly, in such models the observed smallness of the active neutrino masses, together with the high-multiplicity of the final states, leads in large parts of the viable parameter space of such models to the prediction of long-lived charged particles, that leave highly ionizing tracks in the detectors. We focus on one particular 1-loop neutrino mass model in this class and discuss its LHC phenomenology in some detail.
