•Generation of coupling files

The amplitude is transformed to FeynArts notation:

mfa = FCToFA[resul] ;

Terms are collected according to momenta:

mfacoll = MomentaCollect[mfa, ParticlesNumber -> 3, PerturbationOrder -> 2] ;

The coupling vectors for the FeynArts model files are generated and saved:

gencoup = GenericCoupling[mfacoll] ; gencoup

{p _ 1 ° p _ 3, p _ 2 ° p _ 3}

classcoup = Simplify /@ ClassesCoupling[mfacoll] ;

$VeryVerbose = 2 ;

CheckF[gencoup, XName[VertexFields -> {PseudoScalar[0][0], PhiMeson[0], Scalar[1][0]}, PerturbationOrder -> 4, PhiModel -> ChPTW3, XFileName -> Automatic] <> ".Gen"] ;
