标准模型希格斯玻色子-膨胀子和暗物质

The Standard Model Higgs Boson-Inflaton and Dark Matter

T. E. Clark, Boyang Liu, S. T. Love, T. ter Veldhuis

摘要:

标准模型希格斯玻色子可以作为慢卷暴胀模型的暴胀子场,只要它表现出与引力标量曲率的大的非最小耦合。希格斯玻色子的自相互作用及其与作为暗物质来源的标准模型单重标量的耦合受到宇宙学的约束。这些界限,可能比那些由真空稳定性和微扰平凡性单独产生的界限更严格,仍然允许希格斯玻色子的质量值,这应该是在大型强子对撞机访问。随着希格斯玻色子与暗物质的耦合增强,与宇宙学数据一致的较低的希格斯玻色子质量值是允许的。

英文摘要:

The standard model Higgs boson can serve as the inflaton field of slow roll inflationary models provided it exhibits a large non-minimal coupling with the gravitational scalar curvature. The Higgs boson self interactions and its couplings with a standard model singlet scalar serving as the source of dark matter are then subject to cosmological constraints. These bounds, which can be more stringent than those arising from vacuum stability and perturbative triviality alone, still allow values for the Higgs boson mass which should be accessible at the LHC. As the Higgs boson coupling to the dark matter strengthens, lower values of the Higgs boson mass consistent with the cosmological data are allowed.
