针对具有 SU(5) ⊗ SU(3)H 对称性的模型，讨论了夸克和轻子通过与假设的超重费米子混合产生质量的新机制。所提出的水平 SU(3)H 对称破缺模式导致了 Fritzsch 先前提出的形式的质量矩阵。导出了夸克和轻子质量与混合角之间的关系。与夸克和带电轻子相反，中微子质量遵循逆“水平”层次结构：mνe⪢mνμ⪢mντ。
A new mechanism of quark and lepton mass generation via their mixing with hypothetical superheavy fermions is discussed for the model with the SU(5) ⊗ SU(3)Hsymmetry. The proposed pattern of the horizontal SU(3)Hsymmetry breaking leads to mass matrices of the form previously suggested by Fritzsch. The relations between the quark and lepton masses and mixing angles are derived. In contrast with quarks and charged leptons neutrino masses obey the inverse “horizontal” hierarchy: mνe⪢ mνμ⪢ mντ.
