Higgs质量的一种可能的宇宙学引力弛豫解释

A possible interpretation of the Higgs mass by the cosmological attractive relaxion

Fa Peng Huang, Yifu Cai, Hong Li, Xinmin Zhang

摘要:

最近,人们提出了一种新的想法,通过宇宙学暴胀和轴子周期势来放松电弱等级问题。在这里,我们进一步假设只需要吸引暴胀来解释希格斯玻色子玻色子的轻质量,而不需要轴子场的特定周期势。早期宇宙的引力暴胀使希格斯玻色子的质量从早期宇宙的大值下降到现在的小值,希格斯质量是宇宙的一个演化参数。因此,小希格斯质量可以从技术上起源于宇宙学演化,而不是动力学对称或人择学。进一步,我们研究了未来轻子对撞机可能产生的碰撞信号或约束,以及μ子反常磁矩可能产生的约束。本文还讨论了一个具体的引力弛豫模型,该模型与Planck 2015年的数据一致.

英文摘要:

Recently, a novel idea has been proposed to relax the electroweak hierarchy problem through the cosmological inflation and the axion periodic potential. Here, we further assume that only the attractive inflation is needed to explain the light mass of the Higgs boson, where we do not need a specified periodic potential of the axion field. Attractive inflation during the early universe drives the Higgs boson mass from the large value in the early universe to the small value at present, where the Higgs mass is an evolving parameter of the Universe. Thus, the small Higgs mass can technically originate from the cosmological evolution rather than dynamical symmetry or anthropics. Further, we study the possible collider signals or constraints at future lepton collier and the possible constraints from the muon anomalous magnetic moment. A concrete attractive relaxion model is also discussed, which is consistent with the data of Planck 2015.
