Hello everyone,
I have written a FeynRules model.fr file in terms of weyl spinors.I have loaded it in the mathematica session with no problem, the lagrangian and the vertices which FeynRules derives in terms of weyl spinors seem OK. But in order to use the model for FeynArts and FeynCalc I have to convert to dirac notation.I use the command Ld=WeyltoDirac["lagrangian"] to do it but when FeynRules calculates vertices for Ld all the vertices including fermions are omitted.I do not have any idea where the problem comes from.Would you please help me about this?Thanks in advance.
Regards
