FEYN CALC SYMBOL

Amplitude


is a database of Feynman amplitudes. Amplitude["name"] returns the amplitude corresponding to the string "name". A list of all defined names is obtained with Amplitude[]. New amplitudes can be added to the file "Amplitude.m". It is strongly recommended to use names that reflect the process. The option Gauge 1 means `t Hooft Feynman gauge; Polarization 0 gives unpolarized OPE-type amplitudes, Polarization 1 the polarized ones.
