A new possibility for light-quark Dark Matter

Abstract

Despite many decades of study the physical origin of "dark matter" in the Universe remains elusive. In this letter we calculate the properties of a completely new dark matter candidate - Bose-Einstein condensates formed from a recently discovered bosonic particle in the light-quark sector, the ${\mathbf{d}}^{\ast }(2380)$ hexaquark. In this first study, we show stable ${\mathbf{d}}^{\ast }(2380)$ Bose-Einstein condensates could form in the primordial early universe, with a production rate sufficiently large that they are a plausible new candidate for dark matter. Some possible astronomical signatures of such dark matter are also presented.
