Hello, I have Mathematica 8. I type this:
Tr[(GSD[p] + m).GAD[\[Mu]].(GSD[q] - m).GAD[\[Nu]]]
I just copy paste that from feyncalc guide. However, the result is:
4 DiracTrick(
m + \!\(TraditionalForm\`"\[Gamma]"\)\[CenterDot]\!\(\
TraditionalForm\`p\), \[Gamma]^\!\(TraditionalForm\`\(TraditionalForm\
\`\[Mu]\)\), \
\!\(TraditionalForm\`"\[Gamma]"\)\[CenterDot]\!\(TraditionalForm\`q\) \
- m, \[Gamma]^\!\(TraditionalForm\`\(TraditionalForm\`\[Nu]\)\),
InsideDiracTrace -> True, Factoring -> False,
FeynCalcInternal -> True, DiracCanonical -> False,
InsideDiracTrace -> True, Factoring -> False,
FeynCalcInternal -> True, DiracCan
There is this annoying InsideDiracTrace, FeynCalcInternal, etc. Someone in this thread has the same problem, but he solves it with Mathematica 5. I only have Mathematica 8. How to proceed? please please help me. Thanx
