Lifshitz型规范理论中的费米子质量族

Fermion Mass Hierarchy in Lifshitz Type Gauge Theory

Kunio Kaneta, Yoshiharu Kawamura

摘要:

研究了含有额外标量场的标准模型的Lifshitz型推广中费米子质量等级和味混合的起源。我们表明,层次结构可以起源于可重正化的相互作用。与Froggatt-Nielsen机制相反,关联算符的维数越高,费米子的质量就越重。在没有引入右手中微子的情况下,左手中微子的质量很小。

英文摘要:

We study the origin of fermion mass hierarchy and flavor mixing in a Lifshitz type extension of the standard model including an extra scalar field. We show that the hierarchical structure can originate from renormalizable interactions. In contrast to the Froggatt-Nielsen mechanism, the higher the dimension of associated operators, the heavier the fermion masses. Tiny masses for left-handed neutrinos are obtained without introducing right-handed neutrinos.
