中性子暗物质与电弱标度的自然性

Neutralino dark matter and naturalness of the electroweak scale

Geneviève Bélanger, Cédric Delaunay, Andreas Goudelis

摘要:

如果弱尺度超对称性(SUSY)要以某种方式解释希格斯玻色子质量的辐射稳定性,那么很可能应该考虑SUSY模型的非最小变体。在宇宙的暗物质是由中性伴子组成的假设下,最近的直接探测实验以及暗物质丰度测量的限制对最小超对称模型的自然性提出了严格的限制。我们表明,即使是非极小模型引入适度解耦的新物理,以解决希格斯玻色子质量问题面临类似的问题,有一个有趣的例外。

英文摘要:

If weak scale supersymmetry (SUSY) is to somehow explain the radiative stability of the Higgs boson mass, it is likely that non-minimal variants of SUSY models should be considered. Under the assumption that the dark matter of the universe is comprised of neutralinos, recent limits from direct detection experiments as well as dark matter abundance measurements place stringent bounds on the naturalness of minimal supersymmetric models. We show that even non-minimal models introducing moderately decoupled new physics in order to address the Higgs boson mass problem face similar issues, with one interesting exception.
