Hi Sun,
thanks for reporting this issue. The bug is now fixed
in the development version
<https://github.com/FeynCalc/feyncalc/commit/7a1abf7a6e4e32cb871538fb5c8457c690419ecf>
and
FourDivergence[FV[k1, alpha] FV[k1, beta]
(SP[k1, q] + 2 SP[k2, q]),
FV[q, gamma]]
returns
Pair[LorentzIndex[alpha],
Momentum[k1]]*Pair[LorentzIndex[beta],
Momentum[k1]]*Pair[LorentzIndex[gamma],
Momentum[k1]] +
2*Pair[LorentzIndex[alpha],
Momentum[k1]]*Pair[LorentzIndex[beta],
Momentum[k1]]*Pair[LorentzIndex[gamma],
Momentum[k2]]
as it should.
Cheers,
Vladyslav
