镜像机制中轻子的CP性质

CP Properties of Leptons in Mirror Mechanism

Igor T. Dyatlov

摘要:

通过重镜像费米子的中间态构造夸克和轻子质量矩阵能够再现弱混合矩阵(CKM和PMNS矩阵)的主要定性性质。再现包括CKM矩阵元素的层次结构,PMNS矩阵的一般形式,涉及中微子混合角θ 13的小,并导致非常小的中微子质量。对于轻子,这些性质只出现在SM中微子的狄拉克性质及其逆谱中。在这样的轻子系统中,不仅自发的镜像对称破坏和观察到的带电轻子的质量等级(e,μ,τ)决定了PMNS矩阵的结构,而且还允许评估其允许的复杂性,即轻子的CP性质。PMNS矩阵则不包含Majorana相位,其Dirac相位δ_{CP}对应于|\sin δ_{CP}|,它明显小于单位。

英文摘要:

Formation of quark and lepton mass matrices through intermediate states of heavy mirror fermions is capable of reproducing main qualitative properties of weak mixing matrices (CKM and PMNS matrices). The reproduction includes the hierarchy of CKM matrix elements, a general form of the PMNS matrix, involving the smallness of the neutrino mixing angle θ_{13}, and leads to very small neutrino masses. For leptons, these properties appear only for the Dirac nature of SM neutrino and its inverse spectrum. In such a lepton system, not only do spontaneous mirror symmetry violation and the observed mass hierarchy of charged leptons (e,μ,τ) govern the structure of the PMNS matrix but also permit assessment of its allowed complexity, that is, the CP properties of leptons. The PMNS matrix then contains no Majorana phases and its Dirac phase δ_{CP} corresponds to |\sinδ_{CP}|, which is significantly smaller than unity.
