=== Description ===
This project contains the complete set of Feynman rules for all five scalar leptoquarks, implemented in [https://feynrules.irmp.ucl.ac.be 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 [https://cp3.irmp.ucl.ac.be/projects/madgraph/ MadGraph_aMC@NLO] and [http://www.feynarts.de FeynArts] are included.

=== Model files ===
-  [https://feynrules.irmp.ucl.ac.be/attachment/wiki/SLQrules/SLQrules.fr SLQrules.fr]: This is the main model file. It contains the LQ parameter, LQ field definitions as well as their interactions. 
-  [https://feynrules.irmp.ucl.ac.be/attachment/wiki/SLQrules/SM.fr SM.fr]: This is the [https://feynrules.irmp.ucl.ac.be FeynRules] SM model file. It is needed to determine the interactions between the LQs and the SM particles. 
-  [https://feynrules.irmp.ucl.ac.be/attachment/wiki/SLQrules/UFO.zip UFO.zip]: This archive contains the files needed for [https://cp3.irmp.ucl.ac.be/projects/madgraph/ MadGraph_aMC@NLO] phenomenology studies.
