SUMMARY

The FeynRules package is a definitive tool for generating Feynman rules from Lagrangians, producing model files compatible with FeynArts and CalcHEP/CompHEP. For users without access to Mathematica, LanHEP serves as an alternative solution for the same purpose. Both tools streamline the process of deriving vertices from Lagrangian formulations, making them essential for theoretical physicists working in particle physics.

PREREQUISITES
  • Understanding of Lagrangian mechanics
  • Familiarity with Feynman diagrams
  • Basic knowledge of particle physics
  • Experience with software tools like Mathematica or similar computational packages
NEXT STEPS
  • Explore the FeynRules package documentation for detailed usage instructions
  • Learn how to convert FeynRules output for use in FeynArts
  • Investigate LanHEP's capabilities and installation process
  • Study examples of Lagrangians and their corresponding Feynman rules
USEFUL FOR

The discussion is beneficial for theoretical physicists, researchers in particle physics, and anyone involved in computational modeling of particle interactions using Lagrangians.

Gents,

Is there such software package or something like that... when you input the lagrangian it gives you the vertecies (Feynman rules)...

Thanks

If you don't have a copy of Mathematica handy, there's also LanHEP.
