Dark matter and dark energy from quark bag model

TL;DR

This paper explores how relic quark-gluon objects, either as isolated nuggets or uniformly spread, could explain dark matter and dark energy, potentially accounting for the Universe's accelerated expansion.

Contribution

It introduces a quark bag model framework to describe relic colored objects as candidates for dark matter and dark energy, offering a novel explanation for cosmic acceleration.

Findings

Quark-gluon nuggets can serve as dark matter candidates.

Uniform colored objects can drive late-time cosmic acceleration.

The model links particle physics with cosmological phenomena.

Abstract

We calculate the present expansion of our Universe endowed with relict colored objects - quarks and gluons - that survived hadronization either as isolated islands of quark-gluon "nuggets", or spread uniformly in the Universe. In the first scenario, the QNs can play the role of dark matter. In the second scenario, we demonstrate that uniform colored objects can play the role of dark energy providing the late-time accelerating expansion of the Universe.
