Partially Composite Dark Matter

TL;DR

This paper explores a model where dark matter particles contribute to the Higgs potential, balancing the top quark contribution, which naturally explains dark matter abundance and suggests promising detection prospects.

Contribution

It introduces a scenario where dark matter contributions balance the top quark in Higgs potential generation, offering a novel approach within composite Higgs models.

Findings

Dark matter relic abundance matches observations.

Direct detection prospects are promising.

Balance between dark matter and top quark contributions is feasible.

Abstract

In a class of theories where the Higgs field emerges as a pseudo Nambu-Goldstone boson, it is often assumed that interactions to generate the top Yukawa coupling provide the Higgs potential as well. Such a scenario generically requires a little cancellation in the leading contribution to the Higgs potential, and the electroweak scale is generated by the balance between the leading and the subleading contributions. We, instead, consider the possibility that the contribution from the dark matter particle balances against that from the top quark. The thermal relic of the new particle explains the abundance of dark matter in a consistent region of the parameter space, and the direct detection is found to be promising.
