--> DM@NLO is a numerical code to compute the annihilation cross-section of the neutralino in the Minimal Supersymmetric Standard Model at next-to-leading order in α s . The package is designed to work with micrOMEGAs in order to evaluate the relic density of the neutralino including the corrections in QCD and SUSY-QCD. An interface to DarkSUSY is under development. Currently, DM@NLO includes the following classes of processes: gaugino pair-annihilation into quark pairs [1,2,3,6], gaugino-squark coannihilat
DM@NLO is a numerical code dedicated to precision calculations of dark matter (DM) (co)annihilation cross-sections and elastic dark matter-nucleon scattering amplitudes in the Minimal Supersymmetric (SUSY) Standard Model (MSSM) at next-to-leading order (NLO) in perturbative (SUSY) QCD. If the annihilating initial particles carry an electric or colour charge, the Sommerfeld enhanced cross section is included as well and can be matched to the NLO cross section. The code is written in Fortran 77 and includes a
