Electroweak symmetry breaking and cold dark matter from hidden sector technicolor

TL;DR

This paper proposes a model where electroweak symmetry breaking arises from a hidden sector gauge theory, which also provides a candidate for cold dark matter through lightest mesons, with multiple Higgs-like scalars potentially decaying into dark matter pairs.

Contribution

It introduces a hidden sector technicolor model where EWSB is caused by dimensional transmutation and identifies hidden mesons as dark matter candidates.

Findings

Hidden sector gauge dynamics induce EWSB.

Lightest hidden mesons can serve as cold dark matter.

Multiple Higgs-like scalars may decay into dark matter pairs.

Abstract

We consider models with a vectorlike confining gauge theory in the hidden sector, and demonstrate that the origin of the electroweak symmetry breaking (EWSB) is due to the dimensional transmutation in the hidden sector gauge theory, and the lightest mesons in the hidden sector could be a good cold dark matter (CDM) candidate. There would be more than one neutral Higgs-like scalar bosons, and they could decay mainly into the CDM pair, if that decay channel is kinemtically allowed.
