FeynCalc is a Mathematica package for algebraic calculations in elementary particle physics.

Some of the features of FeynCalc are:

• Passarino-Veltman reduction of one-loop amplitudes to standard scalar integrals
• Tools for frequently occuring tasks like Lorentz index contraction, color factor calculation, Dirac matrix manipulation and traces, etc.
• Tensor and Dirac algebra manipulations (including traces) in 4 or D dimensions
• Generation of Feynman rules from a lagrangian
• Tools for non-commutative algebra
• SU(N) algebra
• Tables of integrals, convolutions and Feynman rules
• Special convolution, Mellin transform and other integral tables
• Tools for calculating 2-loop propagator-type diagrams
• FORM and FORTRAN code generation
• Translation to and from FORM

FeynCalc is maintained and developed by Rolf Mertig and Frederik Orellana.

For more on applicability, implementation and usage, see the documentation.
