高维模型中的三族统一

Three family unification in higher dimensional models

Yukihiro Mimura, S. Nandi

摘要:

在轨道折叠模型中,通过高维超对称规范理论的紧化,规范场、希格斯场和物质场可以统一为一个多重态。我们研究了三族手征费米子如何在规范多重态中统一。体规范相互作用包括汤川相互作用,在电弱对称破缺后产生夸克和轻子的质量。体Yukawa相互作用具有源于体R对称性或体规范对称性的整体或规范味对称性,并且Yukawa结构受到限制。当整体和规范味对称被轨道紧化破缺时,包含标准模型规范对称性的剩余规范对称性受到限制。体味对称性的限制可以解释费米子的质量等级。

英文摘要:

In orbifold models, gauge, Higgs and the matter fields can be unified in one multiplet from the compactification of higher dimensional supersymmetric gauge theory. We study how three families of chiral fermions can be unified in the gauge multiplet. The bulk gauge interaction includes the Yukawa interactions to generate masses for quarks and leptons after the electroweak symmetry is broken. The bulk Yukawa interaction has global or gauged flavor symmetry originating from the R symmetry or bulk gauge symmetry, and the Yukawa structure is restricted. When the global and gauged flavor symmetries are broken by orbifold compactification, the remaining gauge symmetry which contains the standard model gauge symmetry is restricted. The restrictions from the bulk flavor symmetries can provide explanations of fermion mass hierarchy.
