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 SUSY-QCD corrections to neutralino (co)annihilation processes including Coulomb enhancement effects. We demonstrate that these corrections can have significant impact on the cosmologically favoured MSSM parameter space and are thus of general interest…

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

Theoretical uncertainties in the calculation of supersymmetric dark matter observables

We estimate the current theoretical uncertainty in supersymmetric dark matter predictions by comparing several state-of-the-art calculations within the minimal supersymmetric standard model (MSSM).

The pMSSM10 after LHC run 1

The pMSSM10 is able to provide a supersymmetric interpretation of (g-2)_\mu $$(g- 2)μ, unlike the CMSSM, N UHM1 and NUHM2, and shows that the cold dark matter density and the XENON100 and LUX searches for spin-independent dark matter scattering are mainly provided by the lightest neutralino.
