The Higgs portal and an unified model for dark energy and dark matter

TL;DR

This paper proposes a unified model where the Higgs boson interacts with a singlet scalar field, linking dark energy as a classical quintessence field and dark matter as its quantum excitation, produced via Higgs coupling.

Contribution

It introduces a novel unified framework connecting dark energy and dark matter through Higgs portal interactions with a quintessence field.

Findings

Dark energy is modeled as a classical rolling scalar field.

Dark matter arises as quantum excitations of the scalar field.

The model provides a mechanism for dark matter production via Higgs coupling.

Abstract

We examine a scenario where the Higgs boson is coupled to an additional singlet scalar field which we identify with a quintessence field. We show that this results in an unified picture of dark matter and dark energy, where dark energy is the zero-mode classical field rolling the usual quintessence potential and the dark matter candidate is the quantum excitation (particle) of the field, which is produced in the universe due to its coupling to the Higgs boson.
