Description
After brief introduction with dark matter (DM) problem and talking about methods of DM detection, we propose a model which is a minimal generalization of the standard model (SM) with two cold dark matter candidates. One of these candidates is a eutral Fermion and the other is a neutral singlet scalar. Both scalar and Fermionic fields interact with standard model particles. In addition, these two particles interact with each other. Finally, solving Boltzmann equations for scalar and Fermionic fields, we obtain the relic density of these fields in the Universe. We fix the parameters of our model so that dark matter density will be compatible with WMAP and Planck data.
