Description
In the standard approach, theoretical predictions of the dark matter relic abundance for freeze-out scenarios are performed by only using (effective) tree-level annihilation cross sections as input for the 0-moment of the Boltzmann equation, i.e. the number density equation. To allow for the future automatization of next-to-leading order calculations to the relic density, we present a general extension of the Catani-Seymour dipole subtraction method to massive initial-states and highlight the importance of higher-order corrections for relevant (co)annihilation scenarios in the Minimal Supersymmetric Standard Model. In addition, we discuss the impact on the relic density when the Boltzmann equation is solved on the level of the phase space distribution instead, taking into account the effect of elastic (self)-scattering processes.
