Hello,
I have to calculate QED diagrams consisting of photons coming out from an
electron loop (up to 12 photons!). I would like FeynCalc to help me to
perform Dirac matrices traces and index contractions.
I don't know how to enter the values of the integrals (a global factor times
a tensor structure, consisting of all index permutations), since there is a
lot of permutations of these indices.
Does FeynCalc have any template of dimensional regularization integrals?
Does FeynCalc have any function to perform automatic permutations of
indices?
Thank you.
