Precision predictions for dark matter in the MSSM
|
| 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 user-friendly C++ interface as well as a SLHA interface. DM@NLO can easily be linked with micrOMEGAs in order to evaluate the dark matter relic density including the above-mentioned corrections.
