论文摘要

对右中微子肿块的两环影响可能会对低能现象学产生影响,尤其是当右中微子质谱在截止量表上非常分层时。在这种情况下,较轻的右撇子中微子的物理质量可以由较重的量子效应主导。此外,如果最重的右中微子质量在普朗克量表附近,则两层循环对右中微子质量的影响通过Seesaw机制产生,这是一种活跃的中微子质量,是实验值的球形。在本文中,我们研究了Planck-Scale Lepton数字破坏方案的扩展,该方案是其他Higgs Doublets(inter或not)的扩展。我们发现,在合理的假设下,这些模型同时导致了总体中微子质量量表,并在定性协议中与观察结果达成了中微子质量层次结构。

Two-loop effects on the right-handed neutrino masses can have an impact on the low-energy phenomenology, especially when the right-handed neutrino mass spectrum is very hierarchical at the cut-off scale. In this case, the physical masses of the lighter right-handed neutrinos can be dominated by quantum effects induced by the heavier ones. Further, if the heaviest right-handed neutrino mass is at around the Planck scale, two-loop effects on the right-handed neutrino masses generate, through the seesaw mechanism, an active neutrino mass which is in the ballpark of the experimental values. In this paper we investigate extensions of the Planck-scale lepton number breaking scenario by additional Higgs doublets (inert or not). We find that under reasonable assumptions these models lead simultaneously to an overall neutrino mass scale and to a neutrino mass hierarchy in qualitative agreement with observations.
