I have installed FeynCalc 8.2.0 in Mathematica 10.
I have tried:
In:= Tr[DiracTrace[GA[a, b]]] // StandardForm
Out//StandardForm= 16 Pair[LorentzIndex[a], LorentzIndex[b]]
The result should be
4 Pair[LorentzIndex[a], LorentzIndex[b]]
Traces of four gamma matrices also gives the same factor of four.
Am I doing something wrong?
I am sorry if I am doing a dummy question, I am new to FeynCalc.
Thanks in advance.
