Cold Dark Matter: A Gluonic Bose--Einstein Condensate in Anti-de Sitter Space Time

TL;DR

This paper proposes that dark matter can be explained as a gluonic Bose-Einstein condensate resulting from QCD effects during the early universe's phase transition, offering a new cosmological model aligning particle physics with cosmology.

Contribution

It introduces a novel interpretation of dark matter as a gluonic Bose-Einstein condensate, linking QCD phenomena to cosmological observations without extra ad hoc fields.

Findings

Dark/Visible matter ratio of 11/2 derived from the model

Gluons acquire vibrational mass in the condensate

Supports a unified particle physics and cosmology framework

Abstract

In the same way as the realization of some of the famous gedanken experiments imagined by the founding fathers of quantum mechanics has recently led to the current renewal of the interpretation of quantum physics, it seems that the most recent progresses of observational astrophysics can be interpreted as the realization of some cosmological gedanken experiments such as the removal from the universe of the whole visible matter or the cosmic time travel leading to a new cosmological standard model. This standard model involves two dark components of the universe, dark energy and dark matter. Whereas dark energy is usually associated with the cosmological constant, we propose to explain dark matter as a pure QCD effect, namely a gluonic Bose Einstein condensate, following the transition from the quark gluon plasma phase to the colorless hadronic phase. Our approach not only allows us to assume a ratio Dark/Visible equal to 11/2 but also provides gluons (and di-gluons, viewed as quasi-particles) with an extra mass of vibrational nature. Such an interpretation would comfort the idea that, apart from the violation of the matter/antimatter symmetry satisfying the Sakharov's conditions, the reconciliation of particle physics and cosmology needs not the recourse to any ad hoc fields, particles or hidden variables.
