论文摘要
如果通过涉及沉重的费米昂单元的所谓的seesaw机制，可以将标准模型（SM）中微子的轻度（SM）中微子的质量高度理解。如果新的物理学仅少量违反了Baryon减去Lepton的数字，那么沉重的费米昂单人以及SM中微子分为Quasi-dirac State成对。在费米式的单元的规模上，这种准底漆可以在其衰减中增强CP违规，并且可以通过谐振的瘦素生成成功产生宇宙物质 - 抗反感的不对称性。在较低的尺度上，这种准底片会导致较小的SM中微子质量分裂，可以在振荡实验中进行探测。值得注意的是，与太阳和大气中微子振荡相关的制度上，生存的静脉生成的参数空间跨越。
The lightness of the Standard Model (SM) neutrinos could be understood if their masses were to be generated by new physics at a high scale, through the so-called seesaw mechanism involving heavy fermion singlets. If new physics violates baryon minus lepton number by only a small amount, the heavy fermion singlets as well as the SM neutrinos split into pairs of quasi-Dirac states. At the scale of the fermion singlets, this quasi-Diracness allows to enhance CP violation in their decays and the cosmic matter-antimatter asymmetry can be successfully generated through resonant leptogenesis. At lower scale, this quasi-Diracness results in small SM neutrino mass splitting which can be probed in oscillation experiments. Remarkably, the parameter space for viable leptogenesis spans over the regime relevant for solar and atmospheric neutrino oscillations.
