用单重标量暗物质研究电弱真空亚稳态

A study of electroweak vacuum metastability with a singlet scalar dark matter

Najimuddin Khan, Subhendu Rakshit

摘要:

我们研究了几个方面的电弱真空亚稳性时,额外的规范单重标量,一个可行的候选人的暗物质粒子,被添加到粒子物理学的标准模型,这被认为是有效的普朗克尺度。相图绘制不同的参数空间,并在此基础上,我们以图形方式展示了如何的置信水平,在该水平下,电弱真空的稳定性被排除在外,取决于这样的新的物理参数。

英文摘要:

We study several aspects of electroweak vacuum metastability when an extra gauge singlet scalar, a viable candidate for a dark matter particle, is added to the standard model of particle physics, which is assumed to be valid up to the Planck scale. Phase diagrams are drawn for different parameter spaces, and based on that, we graphically demonstrate how the confidence level, at which stability of electroweak vacuum is excluded, depends on such new physics parameters.
