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.

Model files

  • SLQrules.fr: This is the main model file. It contains the LQ parameter, LQ field definitions as well as their interactions.
  • SM.fr: This is the FeynRules SM model file. It is needed to determine the interactions between the LQs and the SM particles.
  • UFO.zip: This archive contains the files needed for MadGraph_aMC@NLO phenomenology studies.
  • FeynArts.zip: This archive contains the files needed for FeynArts phenomenology studies.

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.
