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