Hi
I am having trouble using FAToFC in that I either don’t know how to use
it or it
is not in my Libaray. I’m using FeynCalc5Beta1
I create my field and then my amplitude, but when I try to use FAToFC
<<HighEnergyPhysics`FeynCalc`;
$LoadFeynArts=True;
$LoadPhi=True;
\[Mu]D = Topology[1][
Propagator[Incoming][Vertex[1][1],
Vertex[3][5], Field[1]],
Propagator[Outgoing][Vertex[1][3],
Vertex[3][6], Field[3]],
Propagator[Outgoing][Vertex[1][4],
Vertex[3][6], Field[4]],
Propagator[Outgoing][Vertex[1][2],
Vertex[3][5], Field[2]],
Propagator[Internal][Vertex[3][5],
Vertex[3][6], Field[5]]] ->
Insertions[Classes][
Graph[1, Classes == 1][Field[1] -> F[2,
{2}], Field[2] -> -F[1, {2}],
Field[3] -> -F[2, {1}], Field[4] ->
F[1, {1}], Field[5] -> V[3]]];
CreateFeynAmp[\[Mu]D]
Then I try to convert the amplitude using
FAToFC[%]
I just get the output of CreateFeynAmp
Thanks,
