摘　　要：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 into SO(4)subgroups.In the holographic model,we found that 125 GeV 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 candidates Technicolor Interacting Massive Particles(TIMPs).If we consider the dark matter nuclear spin-independent cross-section in the range of 10^−45∼10^−48cm^2,which can be detected by future experiments,the mass range of TIMPs predicted by the holographic technicolor model is 2∼4 TeV.
