论文摘要
重中性瘦素(HNL)是假设的颗粒,能够解释中微子振荡并提供了产生宇宙重子不对称的机制。由于这种颗粒而引起的量子校正会导致带电的Lepton部门违反风味的过程。基于这些校正随HNL质量生长的事实,我们通过质量和混合角度来改善现有的约束。这使我们能够用多TEV HNL探测瘦素发生参数空间的一部分。我们还表明,如果检测到违反带电的Lepton风味信号,则可以在TEV-PEV质量的很大一部分中推断出HNL参数。
Heavy neutral leptons (HNLs) are hypothetical particles able to explain neutrino oscillations and provide a mechanism for generating the baryon asymmetry of the Universe. Quantum corrections due to such particles give rise to flavor violating processes in the charged lepton sector. Based on the fact that these corrections grow with HNL masses, we improve existing constraints by orders of magnitude in mass and mixing angle. This allows us to probe part of the parameter space of leptogenesis with multi-TeV HNLs. We also show that one will be able to infer HNL parameters in a significant portion of the parameter space for TeV-PeV masses if charged lepton flavor violating signals are detected.
