U(3)-味九标量作为味质谱的起源

U(3)-Flavor Nonet Scalar as an Origin of the Flavor Mass Spectra

Yoshio Koide

摘要:

根据夸克和轻子质量谱起源于U(3)味九重标量Φ的VEV结构的观点,研究了下夸克和带电轻子的质量谱. U(3)味对称性被$Φ$的非零和非简并的VEV自发地完全破缺,而不经过U(3)的任何子群.基于玩具模型研究了(m_e+m_μ+m_τ)/(\sqrt{m_e} + \sqrt{m_μ} + \sqrt{m_τ})^2和\sqrt{m_e m_μm_τ} /(\sqrt{m_e} + \sqrt{m_μ} + \sqrt{m_τ})^3的比值。

英文摘要:

According to an idea that the quark and lepton mass spectra originate in a VEV structure of a U(3)-flavor nonet scalar Φ, the mass spectra of the down-quarks and charged leptons are investigated. The U(3) flavor symmetry is spontaneously and completely broken by non-zero and non-degenerated VEVs of $Φ$, without passing any subgroup of U(3). The ratios (m_e+m_μ+m_τ)/(\sqrt{m_e}+\sqrt{m_μ}+\sqrt{m_τ})^2 and \sqrt{m_e m_μm_τ}/(\sqrt{m_e}+\sqrt{m_μ}+\sqrt{m_τ})^3 are investigated based on a toy model.
