几何CP破坏

Geometrical CP Violation

Ivo de Medeiros Varzielas, David Emmanuel-Costa

摘要:

自发CP违反阶段,不依赖于希格斯部门的参数-所谓的可计算的阶段-进行了研究。最简单的实现是在具有3个希格斯二重态的模型中,其中标量势在非阿贝尔对称下是不变的。非阿贝尔离散群Delta(54)被示出为导致用Delta(27)获得的可计算相位的已知结构。我们调查的可能性,容纳所观察到的费米子质量和混合。

英文摘要:

Spontaneous CP-violating phases that do not depend on the parameters of the Higgs sector - the so-called calculable phases - are investigated. The simplest realization is in models with 3 Higgs doublets, in which the scalar potential is invariant under non-Abelian symmetries. The non-Abelian discrete group Delta(54) is shown to lead to the known structure of calculable phases obtained with Delta(27). We investigate the possibily of accommodating the observed fermion masses and mixings.
