Hi,
I’ve encountered some strange behaviour using OneLoopSimplify. The following code is problematic:
OneLoopSimplify[ FVD[p, \[Mu]] SPD[p, k] FAD[{p}, {p, m}], p]
The output is zero. However, if you factor out the vector k (which of course is a constant in this integration) and therefore evaluate
OneLoopSimplify[ FV[p, \[Mu]] FV[p, \[Nu]] FAD[{p}, {p, m}], p]
the result is the expected non-zero stuff: the metric tensor/ (D (p^2 - m^2)).
I’m using FeynCalc 6.0.0 under mathematica 6.
If there is a work around that would be great (and apologies if I am just stupid.)
Donal.
