Hello, I am confused about the differences in the output of OneLoop and TID & ToPaVe
in an amplitude where I use the BMHV prescription for gamma5.
trs =DiracTrace[
GAD[a] . GAD[mu] . DiracMatrix[6] . GAD[b] . GAD[nu] .
DiracMatrix[6]]\ \ /. \ DiracTrace -> Tr
amp = Contract[trs FVD[l, a] FVD[k + l, b] FAD[{l, 0}, {k + l, 0}] ]
I don't get the same result if I integrate with OneLoop[l, amp] or if I use TID[amp,l] and ToPaVe...
What is the proper way to treat this amplitude ?
Thanks, Pilar
