Generating BSM collider events
From Particle Wiki
Collider events from processes beyond the standard model (BSM) can be generated using Monte Carlo event generators.
MadGraph5_aMC@NLO
Several existing and configurable BSM models are already available for use in MadGraph5_aMC@NLO. These can be found here. Additional models can be encoded as UFO files, which in turn can be produced with FeynRules.
