Hi
I have a problem with Dirac Trace.I’m using fc5beta3 with
Mathematica6.
When I try to compute the trace of a simple t channel qq->gg
mt2 = FermionSpinSum[
Contract[(mt mtc)/4/
nc^2 g[\[Mu]3, \[Nu]3]
g[\[Mu]4, \[Nu]4] ]] /.
DiracTrace -> Tr;
I get printed in the result also the options of Tr , e,g,
-8 p1.p2 p1.p3 (DiracCanonical->False) (Factoring->False)
(FeynCalcInternal->True) (InsideDiracTrace->True).
The same code seems to run fine with Mathematica 5 though.
Does anybody know how to get rid of the options?
Cheers
Simone
