Composite dark matter from a model with composite Higgs boson

Understand

In a previous paper \cite{Khlopov:2007ic}, we showed how the minimal walking technicolor model (WTC) can provide a composite dark matter candidate, by forming bound states between a -2 electrically charged techniparticle and a $^4He^{++}$.

• We studied the properties of these \emph{techni-O-helium} $tOHe$ "atoms", which behave as warmer dark matter rather than cold.
• In this paper we extend our work on several different aspects.
• We study the possibility of a mixed scenario where both $tOHe$ and bound states between +2 and -2 electrically charged techniparticles coexist in the dark matter density.
