破碎的$S_3$中微子

Broken $S_3$ Neutrinos

H. B. Benaoum

摘要:

最近的测量,强烈支持非零反应堆混合角$θ_{13}$的动机,我们研究了偏离$S_3$中微子离散对称性明确打破中微子质量矩阵与一般的逆循环矩阵。我们发现,非零的$θ_{13}$和非零CP破坏参数$J_{CP}$的出现,由于$y_2$和$y_3$之间的差异。我们证明,这是可能的,以获得实验上有利的结果中微子质量和混合角从这个质量矩阵。此外,我们还估算了由该质量矩阵预测的有效质量$m_β$和$m_{ββ}$以及中微子总质量$\sum |m_i|$。

英文摘要:

Motivated by recent measurements which strongly support a nonzero reactor mixing angle $θ_{13}$, we study a deviation from $S_3$ neutrino discrete symmetry by explicitly breaking the neutrino mass matrix with a general retrocirculant matrix. We show that nonzero $θ_{13}$ and nonzero CP violation parameter $J_{CP}$ arise due to the difference between $y_2$ and $y_3$. We demonstrate that it is possible to obtain the experimentally favored results for neutrino masses and mixing angles from this mass matrix. Furthermore, we estimate the effective masses $m_β$ and $m_{ββ}$ and total neutrino mass $\sum |m_i|$ predicted by this mass matrix.
