Description

This project contains the complete set of Feynman rules for all five scalar leptoquarks, implemented in FeynRules. We include the LQ-LQ-Higgs(-Higgs) interactions and the resulting LQ mass eigenstates, the couplings to the SM gauge bosons and fermions as well as the LQ-LQ-LQ(-Higgs) and LQ-LQ-LQ-LQ interactions. The Mathematica notebook to determine and export the Feynman rules as well as the model files for MadGraph_aMC@NLO and FeynArts are included.

Publication

We published a description of this project and the resulting Feynman rules for scalar leptoquarks in ArXiv:2105.04844. Please cite this article (Crivellin:2021tmz) when using any of the contents provided here.

Model files

  • SLQrules.fr: This is the main model file. It contains the scalar LQ parameters, field definitions as well as the complete Lagrangian.
  • SM.fr: This is the FeynRules SM model file. It is needed to determine the interactions between the LQs and the SM particles.
  • SLQrules.nb: This is an example Mathematica notebook that loads and calculates the Feynman rules and can be used to export the model files.
  • UFO.zip: This archive contains the model files for MadGraph_aMC@NLO phenomenology studies.
  • FeynArts.zip: This archive contains the model files for FeynArts phenomenology studies.

Instructions

More information about the SLQrules.nb Mathematica notebook can be found here, the SLQrules.fr model file is discussed in detail here.
