摘要:

我们将轻子混合矩阵(PMNS矩阵)参数化,用三个参数来描述三个混合角与它们的双极大值或三双极大值的偏差。在此参数化的基础上,我们可以用偏离双峰或三双峰混合的三个参数来确定相应的带电轻子混合矩阵。我们发现能偏离双极大混合矩阵和三双极大混合矩阵的带电轻子混合矩阵具有相似的结构。数值分析表明,这些荷轻子混合矩阵与夸克扇形的CKM矩阵非常接近。

英文摘要:

We parametrize lepton mixing matrix, known as PMNS matrix, in terms of three parameters which account deviations of three mixing angles from their bi-maximal or tri-bimaximal values. On the basis of this parametrization we can determine corresponding charged lepton mixing matrix in terms of those three parameters which can deviate bi-maximal or tri-bimaximal mixing. We find that the charged lepton mixing matrices which can deviate bi-maximal mixing matrix and tri-bimaximal mixing matrix exhibit similar structures. Numerical analysis shows that these charged lepton mixing matrices are close to CKM matrix of quark sector.
