Hi, Vladyslav
Thank you very much for the update.
I have used the development version. Everything quite works well.
However, I still have two questions:
1. After running your codes, I find most of the parameters in “SM_Unitary_Gauge” are modified as FCGV[EL], FCGV[SW], …. Is it to avoid conflicts with other definitions?
2. I find the function LorentzIndexNames in FCFAConvert[] doesn’t work sometimes, in both 9.0.1 and development version, and for both default model and added model. For example, after running the following codes
$LoadFeynArts = True;
«FeynCalc`;
$FAVerbose = 0;
tops3 = CreateTopologies[0, 1 -> 3];
inserttops3 =
InsertFields[
tops3, {F[2, {3}]} -> {F[1, {3}], -F[3, {1,
o}], F[4, {1, o}]},
InsertionLevel -> {Particles}, LastSelections ->
{V[3]}];
FCFAConvert[CreateFeynAmp[inserttops3], ChangeDimension ->
4,
LorentzIndexNames -> {lor}, IncomingMomenta -> {p1},
OutgoingMomenta -> {k, k1, k2}, DropSumOver -> True,
List -> False] // Contract
I find the option LorentzIndexNames doesn’t work if I set OutgoingMomenta -> {k, k1, k2} or {k0, k1, k2}, but not {k3,k1,k2}
(The FCGV[] in the output seems also quite strange.)
Thank you again for your time.
Best Regards,
