The LambdaCDM standard model of cosmology involves two dark components of the universe, dark energy and dark matter. Whereas dark energy is usually associated with the (positive) cosmological constant Lambda associated with a de Sitter geometry, we propose to explain dark matter as a pure QCD effect, namely a gluonic Bose Einstein condensate with the status of a Cosmic Gluonic Background (CGB). This effect is due to the trace anomaly viewed as an effective negative cosmological constant determining an Anti de Sitter geometry and accompanying baryonic matter at the hadronization transition from the quark gluon plasma phase to the colorless hadronic phase. Our approach also allows to assume a ratio Dark/Visible equal to 11/2.

The authors investigate the possibility of dark matter as a pure QCD effect, namely as a gluonic Bose-Einstein condensate. They start off the paper by reviewing results about quantum
field theory on important maximally symmetric space-times, specifically Minkowski space-time with its Poincare symmetry group, de Sitter space with its SO(1,4) symmetry and anti-de SItter space with its SO(2,3) symmetry group. Then they go on to discuss the idea of dark matter as a pure QCD effect. Their approach gives 11/2 for the ratio of the dark to visible matter in the universe.
