Software for calculating Feynman diagrams

Click For Summary
SUMMARY

FeynArts and FeynCalc are free software packages designed for drawing and calculating amplitudes of Feynman diagrams, specifically for tree and one-loop diagrams. While these packages are free, they require Mathematica, which is not free unless accessed through a university's student or employee license. Users seeking to perform calculations related to quantum field theory will find these tools particularly useful for their research and studies.

PREREQUISITES
  • Feynman diagram theory
  • Mathematica software (version not specified)
  • Basic understanding of quantum field theory
  • FeynArts and FeynCalc package installation
NEXT STEPS
  • Install FeynArts and FeynCalc for Mathematica
  • Explore tutorials on drawing Feynman diagrams using FeynArts
  • Learn how to calculate amplitudes with FeynCalc
  • Research quantum field theory principles relevant to Feynman diagrams
USEFUL FOR

Physicists, students in quantum field theory, and researchers looking to visualize and compute Feynman diagrams will benefit from this discussion.

I'd appreciate it very much if someone told me if there is any free software to (draw and) calculate the amplitudes of simple (tree and one loop) Feynman diagrams.

I'm hesitating because I don't know if this is the right place to ask. If it's not, I apologize in advance.

Have you tried the FeynArts and FeynCalc Mathematica packages?

Edit: The packages are free. Of course, Mathematica isn't (it is free for you if your university had student/employee licences - but then your university is paying).
