论文摘要
Singlet标量暗物质自然可以在复合Higgs模型中作为额外的稳定伪-Nambu-Goldstone Boson。我们在基于$ SU(6)/SO(6)$的模型中研究了这种候选者的特性,其光夸克质量是由4-弗里米亚相互作用产生的。耦合中非线性的存在使质量的遗物密度饱和$ 400 <m _ {\ rm dm} <1000 $ GEV,并在直接检测和间接检测中幸存下来。可行的参数区域可达到未来升级的敏感性,例如Xenonnt和LZ。
Singlet scalar Dark Matter can naturally arise in composite Higgs models as an additional stable pseudo-Nambu-Goldstone boson. We study the properties of such a candidate in a model based on $SU(6)/SO(6)$, with the light quark masses generated by 4-fermion interactions. The presence of non-linearities in the couplings allows to saturate the relic density for masses $400 < m_{\rm DM} < 1000$ GeV, and survive the bound from Direct Detection and Indirect Detection. The viable parameter regions are in reach of the sensitivities of future upgrades, like XENONnT and LZ.
