Hi Vladyslav,
Thank you for the detailed explanation.
For question.2 After running your code, I still get a strange result
(Spinor[Momentum[k], 0, 1] .
DiracGamma[LorentzIndex[\[Mu]]] .
DiracGamma[7] . Spinor[Momentum[p1],
FCGV[”]”*“FCGV[”*ML], 1]*
Spinor[Momentum[k2],
FCGV[”]”*“FCGV[”*MD], 1] .
DiracGamma[LorentzIndex[\[Mu]]] .
DiracGamma[7] .
Spinor[-Momentum[k1],
FCGV[”]”*“FCGV[”*MU], 1]*
FCGV[”]”*“FCGV[”*EL]^2*FeynAmpDenominator[
PropagatorDenominator[Momentum[k1 + k2],
FCGV[”]”*“FCGV[”*MW]]])/(2*FCGV[”]”*“FCGV[”*SW]^2)
Best
