$SU(2)_L \times SU(2)_R\times SU(4)$电弱模型中的自发SU(2)对称性破坏

Spontaneous SU(2) symmetry violation in the $SU(2)_L \times SU(2)_R\times SU(4)$ electroweak model

Yu. A. Simonov

摘要:

本文从高尺度下的基本规范相互作用出发,提出了一种研究EW复合标量的新方法。假设后者具有群结构$SU(2)_L \times SU(2)_R\times SU(4)$,其中SU(4)是Pati-Salam色轻子群。明确地构造了由瞬子填充的拓扑EW真空,由此得到的费米子质量方程表现出自发的SU(2)味对称性破坏,并可能具有非常大的质量比。

英文摘要:

A new approach to EW composite scalars is developed, starting from the fundamental gauge interaction on high scale. The latter is assumed to have the group structure $SU(2)_L \times SU(2)_R\times SU(4)$ where SU(4) is the Pati-Salam color-lepton group. The topological EW vacuum filled by instantons is explicitly constructed and the resulting equations for fermion masses exhibit spontaneous SU(2) flavor symmetry violation with possibility of very large mass ratios.
