Popis: | In dimension-less theories of dynamical generation of the weak scale, the Universe can undergo a period of low-scale inflation during which all particles are massless and undergo super-cooling. This leads to a new mechanism of generation of the cosmological Dark Matter relic density: super-cooling can easily suppress the amount of Dark Matter down to the desired level. This is achieved for TeV-scale Dark Matter, if super-cooling ends when quark condensates form at the QCD phase transition. Along this scenario, the baryon asymmetry can be generated either at the phase transition or through leptogenesis. We show that the above mechanism takes place in old and new dimension-less models.
