Nature of problem:
Calculation of the relic density of the lightest supersymmetric particle particle in the MSSM.

Solution method:
In solving the Boltzmann equation, relativistic formulae for the thermal average are used. All tree-level processes for annihilation and coannihilation of SUSY particles are included. The cross-sections for all processes are calculated exactly with ComHEP. Two-loop corrections to the Higgs masses are calculated with FeynHiggsFast. QCD corrections to the Higgs width are extracted from HDECAY. A linkd to ISASUGRA is provided as an option to calculate the parameters of the MSSM at the weak scale.

Unusual features:
Depending on the parameters of the model, the program generates additional new code, compiles it and loads it dynamically.

Running time:
0.2 sec.
