Quintessential Axions from a New Confining Force

TL;DR

This paper proposes that nearly massless mesons from a new confining gauge force could serve as a source of dark energy, providing a novel motivation for introducing extra nonabelian gauge groups.

Contribution

It introduces a new confining force that produces mesons capable of explaining dark energy, linking particle physics with cosmological phenomena.

Findings

Massless mesons from the new gauge force can act as dark energy candidates.

The model offers a new perspective on the origin of dark energy.

Additional confining forces may be motivated by cosmological considerations.

Abstract

Almost massless mesons created at the condensation scale of extra nonabelian gauge group can be candidates of dark energy source. This can be another motivation for introducing an additional confining force.
