A new possibility for light-quark Dark Matter
  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 $\mathbf{
d^*(2380)}$ hexaquark. In this first study, we show stable $\mathbf{
d^*(2380)}$ 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.
