Higgs复单重态-二重态模型的真空结构

The vacuum structure of the Higgs complex singlet-doublet model

P. M. Ferreira

摘要:

复单重态-二重态模型是解释暗物质和电弱重子生成的流行理论,其中标准模型粒子内容由复标量规范单重态补充,并施加一定的离散对称性。由此产生的标量势在树级可以具有七种不同类型的最小值,这些最小值可以共存于参数的特定选择。因此,有可能一个给定的最小值不是全局的,而是局部的,并且可能隧穿到更深的极值,从而导致真空不稳定性。详细地解释和讨论了这种富真空结构。

英文摘要:

The complex singlet-doublet model is a popular theory to account for dark matter and electroweak baryogenesis, wherein the Standard Model particle content is supplemented by a complex scalar gauge singlet, with certain discrete symmetries imposed. The scalar potential which results thereof can have seven different types of minima at tree-level, which may coexist for specific choices of parameters. There is therefore the possibility that a given minimum is not global but rather a local one, and may tunnel to a deeper extremum, thus causing vacuum instability. This rich vacuum structure is explained and discussed in detail.
