论文摘要
观察到的Lepton风味混合和CP违规模式强烈表明中微子部门可能存在简单的风味对称性 - 当三个左手中微子田间变换为$ν^{} _ {e \ rm l} \ c $ c $ c $ c $ c = rm时，有效的Majorana Neutrino质量术语会保持不变。美元直接应用这种$μ$ - $τ$反射对称性在规范的seesaw机构中可以帮助很多限制活跃和无菌的主要中微子的风味纹理。本文旨在总结探索这种最小风味对称性的特性，其转化和旋转扩展的最新进展，其通过辐射校正从超高能量量表到电动量量表的辐射校正及其各种现象学意义。
The observed pattern of lepton flavor mixing and CP violation strongly indicates the possible existence of a simple flavor symmetry in the neutrino sector -- the effective Majorana neutrino mass term keeps invariant when the three left-handed neutrino fields transform as $ν^{}_{e \rm L} \to (ν^{}_{e \rm L})^c$, $ν^{}_{μ\rm L} \to (ν^{}_{τ\rm L})^c$ and $ν^{}_{τ\rm L} \to (ν^{}_{μ\rm L})^c$. A direct application of such a $μ$-$τ$ reflection symmetry to the canonical seesaw mechanism can help a lot to constrain the flavor textures of active and sterile Majorana neutrinos. The present article is intended to summarize the latest progress made in exploring the properties of this minimal flavor symmetry, its translational and rotational extensions, its soft breaking effects via radiative corrections from a superhigh energy scale to the electroweak scale, and its various phenomenological implications.
