TL;DR
This paper investigates composite pseudo Nambu-Goldstone bosons as dark matter candidates within dynamical electroweak symmetry breaking models, analyzing their relic abundance, mass bounds, and potential for detection at the LHC.
Contribution
It introduces a detailed analysis of pNGB dark matter candidates in technicolor models, including relic abundance calculations and mass bounds.
Findings
pNGB dark matter candidates can have significant thermal relic abundance
Lower bound of 1 MeV on pNGB mass when Higgs > 115 GeV
Candidates are light enough for production at the LHC
Abstract
We study natural composite cold dark matter candidates which are pseudo Nambu-Goldstone bosons (pNGB) in models of dynamical electroweak symmetry breaking. Some of these can have a significant thermal relic abundance, while others must be mainly asymmetric dark matter. By considering the thermal abundance alone we find a lower bound of MW on the pNGB mass when the (composite) Higgs is heavier than 115 GeV. Being pNGBs, the dark matter candidates are in general light enough to be produced at the LHC.
