摘要:

在$SO(5) \times U(1)$规范-希格斯统一中,$SO(5)$ -旋量费米子(暗费米子)中最轻的中性成分成为宇宙的暗物质,它与观察到的不稳定希格斯玻色子有关。我们表明,遗物丰度的暗物质确定WMAP和普朗克数据再现,低于由LUX直接检测实验放置的界限,由一个模型与一个轻和三个较重($n_F=4$)的暗费米子与最轻的一个质量从2.3 $\,$ TeV到3.1 $\,$ TeV。第五维中的相应Aharonov-Bohm相位$θ_H$的范围为0.097至0.074。$n_F=3$($n_F = 5, 6$)暗费米子的情况产生的残余丰度小于(大于)观察到的极限。

英文摘要:

In the $SO(5) \times U(1)$ gauge-Higgs unification the lightest, neutral component of $n_F$ $SO(5)$-spinor fermions (dark fermions), which are relevant for having the observed unstable Higgs boson, becomes the dark matter of the universe. We show that the relic abundance of the dark matter determined by WMAP and Planck data is reproduced, below the bound placed by the direct detection experiment by LUX, by a model with one light and three heavier ($n_F=4$) dark fermions with the lightest one of a mass from 2.3$\,$TeV to 3.1$\,$TeV. The corresponding Aharonov-Bohm phase $θ_H$ in the fifth dimension ranges from 0.097 to 0.074. The case of $n_F=3$ ($n_F = 5, 6$) dark fermions yields the relic abundance smaller (larger) than the observed limit.
