The Minimal Supersymmetric Standard Model (MSSM) is one of the best motivated extensions of the Standard Model (SM): it is of high predictive power and can explain the main open questions of the SM. For instance, it offers a well-motivated cold dark matter candidate. A crucial question is therefore whether parameter sets within this model can explain the correct amount of relic density with its cold dark matter candidate. Since the mixing character can rapidly change depending on the actual parameter point and consequently has immediate influence on the relic density contribution it is necessary to include one-loop corrections in the calculations of the dark matter observables. In this talk we will discuss two classes of possible scenarios and the impact of the fundamental SUSY parameters on the resulting relic density.
