Interplay of gaugino (co)annihilation processes in the context of a precise relic density calculation

The latest Planck data allow one to determine the dark matter relic density with previously unparalleled precision. In order to achieve a comparable precision on the theory side, we have calculated the full $mathcalO(alpha_s)$ corrections to the most …

Precise Prediction of the Dark Matter Relic Density within the MSSM

With the latest Planck results the dark matter relic density is determined to an unprecedented precision. In order to reduce current theoretical uncertainties in the dark matter relic density prediction, we have calculated next-to-leading order …

Impact of SUSY-QCD corrections on neutralino-stop co-annihilation and the neutralino relic density

We have calculated the full O(alpha_s) supersymmetric QCD corrections to neutralino-stop co-annihilation into electroweak vector and Higgs bosons within the Minimal Supersymmetric Standard Model (MSSM). We performed a parameter study within the …
