Legs

Legs is an option used by the functions FeynmanRules and ExportUFO that determines how many external legs should be considered when computing the Feynman rules. Allowed values are n, {n}, or All, where n is a positive integer.

Details and Options

  • Legs-> nComputes all Feynman rules with at most n external legs.
    Legs-> {n}Computes all Feynman rules with exactly n external legs.
    Legs-> AllComputes all Feynman rules without any restrictions on the number of external legs.
