Holographic Technicolor Model and Dark Matter

TL;DR

This paper develops a holographic model of minimal walking technicolor that successfully predicts a composite Higgs, a small S parameter, and a dark matter candidate TIMP with a mass of 2-4 TeV, potentially detectable in future experiments.

Contribution

It introduces a bottom-up holographic technicolor model that simultaneously explains the Higgs mass, electroweak precision constraints, and predicts a viable dark matter candidate with specific properties.

Findings

Achieves a 125 GeV composite Higgs with small S parameter.

Predicts a large number of TeV-scale particles, including TIMPs.

Identifies a detectable dark matter candidate with mass 2-4 TeV.

Abstract

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.
