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 $\mathrm{SU}(6)/\mathrm{SO}(6)$, with the light quark masses generated by 4-fermion interactions. The presence of nonlinearities in the couplings allows us to saturate the relic density for masses $400<m_{\mathrm{DM}}<1000\mathrm{GeV}$, 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.

SU（6）/ SO（6）复合Higgs模型中的单重态暗物质

复合Higgs模型中自然会产生单重态标量暗物质，作为额外的稳定伪Nambu-Goldstone玻色子。我们基于以下模型研究此类候选人的属性$苏（6）/\mathrm{所以}（6）$，与由4费米子相互作用产生的轻夸克质量有关。耦合中非线性的存在使我们能够饱和质量的文物密度$400<{米}_{\mathrm{DM}}<1000\mathrm{GeV}$，并在直接检测和间接检测的范围内生存。可行的参数区域将达到XENONnT和LZ等未来升级的敏感性。
