  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 for parameter studies and
global fits.
