The source of dark matter found?

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