中微子质量矩阵近似$S_3$对称性的结果

Consequences of Approximate $S_3$ Symmetry of the Neutrino Mass Matrix

Chien-Yi Chen, L. Wolfenstein

摘要:

假设中微子质量矩阵由具有置换对称性$S_{\scriptscriptstyle 3}$的项支配,那么只有当质量是准简并的时,才有可能解释中微子数据。具有近似$μ-τ$对称性的次优势项导致近似的三重极大形式。实验结果进行了讨论。

英文摘要:

Assuming that the neutrino mass matrix is dominated by a term with the permutation symmetry $S_{\scriptscriptstyle 3}$ it is possible to explain neutrino data only if the masses are quasi-degenerate. A sub-dominant term with an approximate $μ-τ$ symmetry leads to an approximate tri-bimaximal form. Experimental consequences are discussed.
