We investigate the strongly coupled minimal walking technicolor model (MWT) in the framework of a bottom-up holographic model, where the global $SU(4)$ symmetry breaks to $SO(4)$ subgroup. In the holographic model, we found that 125GeV composite Higgs particles and small Peskin-Takeuchi $S$ parameter can be achieved simultaneously. In addition, the model predicts a large number of particles at the TeV scale, including dark matter candidate Technicolor Interacting Massive Particles (TIMPs). If we consider the dark matter nuclear spin-independent cross-section in the range of $10^{-45}\sim 10 ^ {-48} $cm$^2$, which can be detected by future experiments, the mass range of TIMPs predicted by the holographic technicolor model is 2 $\sim$ 4 TeV.

全息彩色模型和暗物质

我们在自下而上的全息模型框架中研究了强耦合最小步行技术模型 (MWT),其中全局 $SU(4)$ 对称性突破到 $SO(4)$ 子群。在全息模型中,我们发现可以同时实现 125GeV 复合希格斯粒子和小 Peskin-Takeuchi $S$ 参数。此外,该模型预测了大量 TeV 尺度的粒子,包括暗物质候选 Technicolor Interacting Massive Particles (TIMPs)。如果我们考虑 $10^{-45}\sim 10 ^ {-48} $cm$^2$ 范围内的暗物质核自旋独立截面,这可以被未来的实验检测到,质量范围为全息技术彩色模型预测的 TIMP 为 2 $\sim$ 4 TeV。
