从标准模型临界性看Higgs暴胀

Higgs inflation from Standard Model criticality

摘要:

观测到的希格斯粒子的质量$M_H=125.9\pm0.4$ GeV导致了标准模型的临界性,也就是说,希格斯粒子的势在顶质量$171.3$ GeV的尺度$10^{17\text{--}18}$ GeV附近变得平坦。早些时候,我们已经提出了一个希格斯暴胀的情况下,这种关键性发挥了至关重要的作用。在本文中,我们调查详细的宇宙学预测这种情况下,最新的普朗克和BICEP 2的结果。我们发现,这种情况下可以从运行索引的约束是一致的。利用双圈重整化群方程计算了包含Higgs门标量暗物质的Higgs单圈有效势,并发现了Higgs与暗物质之间的耦合依赖于暴胀参数的约束.

英文摘要:

The observed Higgs mass $M_H=125.9\pm0.4$GeV leads to the criticality of the Standard Model, that is, the Higgs potential becomes flat around the scale $10^{17\text{--}18}$GeV for the top mass $171.3$GeV. Earlier we have proposed a Higgs inflation scenario in which this criticality plays a crucial role. In this paper, we investigate detailed cosmological predictions of this scenario in light of the latest Planck and BICEP2 results. We find that this scenario can be consistent with the constraint from the running index too. We also compute the Higgs one-loop effective potential including the Higgs portal scalar dark matter, with the two-loop renormalization group equations and find a constraint on the coupling between Higgs and dark matter depending on the inflationary parameters.
