Journal reference: Comput. Phys. Commun. 197(2015)239 | ||

Programming language: Mathematica. | ||

Computer: Platforms on which Mathematica is available. | ||

Operating system: Operating systems on which Mathematica is available. | ||

Keywords: BSM, Automated one-loop computation, Ultraviolet counterterms, Rational terms. | ||

Classification: 11.1, 11.6. | ||

External routines: FeynArts-3.7 or above | ||

Does the new version supersede the previous version?: Yes | ||

Nature of problem:The new version of FeynRules renormalises and computes with the new NLOCT package the ultraviolet counterterms and the rational R_{2} terms induced by one-loop amplitudes. The resulting vertices can be exported in the UFO format to event generators such as MadGraph5_aMC@NLO. | ||

Solution method:First, the Lagrangian is renormalized in FeynRules and exported to FeynArts through the corresponding interface. Secondly, the NLOCT package computes the R_{2} and UV vertices using the amplitudes from FeynArts. Finally,
the list of NLO vertices is loaded in FeynRules to be exported in the UFO format. | ||

Reasons for new version:The new version allows the automated generation of any model in the UFO format with all the required ingredients to perform automatically one-loop computation. | ||

Summary of revisions:This new version contains all the elements to perform the computation of the NLO ingredients: A function to perform the renormalization in FeynRules, the NLOCT package computes of the UV and R_{2} vertices and the extended UFO interface adds them in the output. | ||

Restrictions:The model should be renormalizable, i.e. the dimension of the operators should not exceed four, and written in the Feynman gauge. | ||

Running time:The running time ranges from a few minutes for models like the SM to a few hours for more complicated models like the MSSM. |
