Hi,
When I do the following four indices integration
FAD[q1]^2 FAD[-p +
q1] (Pair[LorentzIndex[li1], Momentum[-p + 2
q1]] Pair[
LorentzIndex[li3], LorentzIndex[li5]] +
Pair[LorentzIndex[li1], LorentzIndex[li5]]
Pair[LorentzIndex[li3],
Momentum[2 p - q1]] +
Pair[LorentzIndex[li1], LorentzIndex[li3]]
Pair[LorentzIndex[li5],
Momentum[-p - q1]])
(Pair[LorentzIndex[li2],
Momentum[p - 2 q1]] Pair[LorentzIndex[li4],
LorentzIndex[li5]] +
Pair[LorentzIndex[li2], LorentzIndex[li5]]
Pair[LorentzIndex[li4],
Momentum[-2 p + q1]] +
Pair[LorentzIndex[li2], LorentzIndex[li4]]
Pair[LorentzIndex[li5],
Momentum[p + q1]]) (Pair[LorentzIndex[li3],
Momentum[q1]] Pair[
LorentzIndex[li4], LorentzIndex[li7]] -
Pair[LorentzIndex[li3], LorentzIndex[li4]]
Pair[LorentzIndex[li7],
Momentum[q1]]) (-Pair[LorentzIndex[li3],
LorentzIndex[li8]] Pair[
LorentzIndex[li3], Momentum[q1]] +
Pair[LorentzIndex[li3], LorentzIndex[li3]]
Pair[LorentzIndex[li8],
Momentum[q1]])
with TID, an error message appears instead of the result,
Error! TID has encountered a fatal problem and must abort the computation. The problem reads: “Running tidSingleIntegral failed to achieve full tensor reduction of the unique integrals in …”
How can I do to avoid it?
Many thanks for any help,
