论文摘要
可对撞机可测试的低尺度SeeSAW模型预测了伪dirac重中微子，可以产生Lepton Number保存和Lepton数字违反事件的振荡模式。我们探索是否可以在HL-LHC上解析如此重的中微子 - 抗雷抗振荡。为此，我们对振荡进行了第一个完整的蒙特卡洛模拟，例如几个基准点，并在哪些条件下显示了CMS实验能够发现它们的条件。该工作流程建立在Feynrules模型文件上，用于现象学对称性保护的Seesaw方案（PSPSS）和Madgraph的修补版本，能够模拟重型中微子 - 静脉内抗旋转。我们使用快速检测器模拟Delphes，并提供了统计分析，能够推断模拟数据中振荡的重要性。我们的结果表明，对于小于100美元的巨额中微子质量分裂而言，HL-LHC的重中微子 - 抗抗抗酸振荡的发现前景是有希望的。
Collider testable low-scale seesaw models predict pseudo-Dirac heavy neutrinos, that can produce an oscillating pattern of lepton number conserving and lepton number violating events. We explore if such heavy neutrino-antineutrino oscillations can be resolved at the HL-LHC. To that end, we employ the first ever full Monte Carlo simulation of the oscillations, for several example benchmark points, and show under which conditions the CMS experiment is able to discover them. The workflow builds on a FeynRules model file for the phenomenological symmetry protected seesaw scenario (pSPSS) and a patched version of MadGraph , able to simulate heavy neutrino-antineutrino oscillations. We use the fast detector simulation Delphes and present a statistical analysis capable of inferring the significance of oscillations in the simulated data. Our results demonstrate that, for heavy neutrino mass splittings smaller than about 100 $μ$eV, the discovery prospects for heavy neutrino-antineutrino oscillations at the HL-LHC are promising.
