this might be a stupid question but how do I get Feyncalc 8.0.0 beta3 to
evaluate diagrams generated by the patched 3.4 Feynarts version? I
didn't find anything in the manual of FeynArts or documentation of FeynCalc.
The output of CreateFeynAmp looks a bit weird. Why is there still an
integration although it's a tree level process. Moreover does the output
in the FeynArts manual looks quite different from the one produced here.
And how can i just look at the plain expressions for amplitudes without
doing any sums over external states or so?
Find attached an example.nb
Thanks in advance!
