I noticed that in dimensional regulation, the NDR scheme is adopted in FeynCalc 9.0. When I deal with the DiracTrace below:
DiracTrace[
DiracGamma[LorentzIndex[Lor1, D], D].DiracGamma[Momentum[Lor2, D],
D].DiracGamma[LorentzIndex[Lor3, D], D].DiracGamma[
Momentum[Lor4, D], D].DiracGamma[LorentzIndex[Lor5, D],
D].DiracGamma[Momentum[Lor6, D], D].DiracGamma[5]]
There will be warnings, So how can I deal with the DiracTrace above in dimensional regulation with FC9.0?
Thanks alot!
