Today there are several pieces of evidence for dark matter. One well-known experiment is the measurement of the Dark Matter relic density by the Planck satellite. The talk introduces the *Dark Matter at next-to-leading order* (DM@NLO) project which provides predictions for the dark matter relic density in the MSSM including higher-order corrections.
After an introduction of the project DM@NLO, I will shortly speak about the calculation of the electroweak processes. The main focus will lie on the effects of the electroweak tree-level processes on the relic density of neutralinos within selected scenarios.
