    38 Over 200 2→2 processes were run in a variety of ways. First, each process was compared between the original !LanHEP implementation and the current FeynRules implementation. Second, each process was run across multiple monte-carlos including !CalcHEP, !CompHEP, !MadGraph and Sherpa. Third, each process was run in two different gauges, namely Feynman gauge (in !CalcHEP and !CompHEP) and in unitary gauge (in !CalcHEP, !MadGraph and Sherpa). The cross section was computed for each process and compared to one another. Agreement to better than 1% was found for all processes. The parameters for these calculations were taken as in the model files above. The energies and cuts for these calculations were:
