The relic density of shadow dark matter candidates

We present the results of relic density calculations for cold dark matter candidates coming from a model of dark energy and dark matter, which is described by an asymptotically free gauge group SU(2)Z (QZD) with a coupling constant αZ∼ 1 at very low scale of ΛZ∼10−3eV while αZ∼ weak coupling at high energies. The dark matter candidates of QZD are two fermions in the form of weakly interacting massive particles. Our results show that for masses between 50 and 245 GeV, they can account for either a considerable fraction or the entire dark matter of the Universe.
