Nature of problem:
The program is a module for the FeynRules and MadGraph5_aMC@NLO packages that allows the computation of tree-level decay widths for arbitrary BSM models. The module consists of two parts:
Mathematica version 7 to 9. As the package is a module relying on FeynRules and MadGraph5_aMC@NLO all restrictions of these packages apply.
The computation of the Feynman rules from a Lagrangian, as well as the computation of the decay rates, varies with the complexity of the model, and runs from a few seconds to several minutes. See Section 5 of the present manuscript for more information.
