破镜对称模型中的弱混合矩阵结构

Weak Mixing Matrix Structures in the Broken Mirror Symmetry Model

Igor T. Dyatlov

摘要:

对称性破坏的模型描述了一个系统,可以自发地选择左手或右手的弱电流的字符。对于费米子质量谱的分级结构,这样的镜像对称系统允许再现夸克(CKM矩阵)和轻子(PMNS矩阵)的弱混合矩阵的所有定性性质,并且在此,无需额外的模型参数的数值拟合。CKM矩阵元的等级由夸克各代的等级质量谱直接规定。PMNS矩阵的定性性质是由中微子谱的逆性质(m_3是最小质量)和SM中微子的Dirac性质引起的。中微子混合角θ_13相对较小是由于m_3和带电轻子质量比m_e/m_μ都很小。

英文摘要:

A model of symmetry violation is described for a system that can spontaneously choose the left-handed or right-handed character of weak currents. For the hierarchic structure of fermion mass spectra, such a mirror symmetry system allows reproduction of all qualitative properties of weak mixing matrices for both quarks (CKM matrix) and leptons (PMNS matrix),and at that, without additional numerical fitting of model parameters. The hierarchy of CKM matrix elements is directly stipulated by the hierarchical mass spectrum of quark generations. The qualitative properties of the PMNS matrix arise for the inverse character of the neutrino spectrum (m_3 is the smallest mass) and Dirac nature of SM neutrino. The comparatively small value of the neutrino mixing angle theta_13 is a consequence of the smallness of m_3 and the smallness of the charged lepton mass ratio m_e/m_mu.
