•Generation of coupling files

The amplitude is transformed to FeynArts notation:

mfa = FCToFA[resul] ;

Terms are collected according to momenta:

mfacoll = Collect[mfa /. ParticleMass -> ParticleMassTmp, {_MomentaScalarProduct, ParticleMassTmp[PseudoScalar[1], b___]^2, ParticleMassTmp[PseudoScalar[1], b___] ParticleMassTmp[PseudoScalar[2], a___], ParticleMassTmp[PseudoScalar[2], a___]^2, ParticleMassTmp[PseudoScalar[7], d___]^2, ParticleMassTmp[PseudoScalar[8], c___]^2, ParticleMassTmp[PseudoScalar[11], d___]^2}] /. ParticleMassTmp -> ParticleMass ;

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

gencoup = GenericCoupling[mfacoll] ; gencoup

{p _ 1 ° p _ 5, p _ 2 ° p _ 4, p _ 2 ° p _ 3, p _ 2 ° p _ 5, p _ 1 ° p _ 3, p _ 4 ° p _ 5, p _ 1 ° p _ 4, p _ 3 ° p _ 5, p _ 1 ° p _ 2, p _ 3 ° p _ 4, (m _ K^0^(ó  ))^2, (m _ K^+^(ó  ))^2, (m _ π^(ó  ))^2}

classcoup = ClassesCoupling[mfacoll] ;

$VeryVerbose = 2 ;

CheckF[gencoup, XName[VertexFields -> {PhiMeson[0], PhiMeson[0], PhiMeson[0], PhiMeson[0], PhiMeson[0]}, PerturbationOrder -> 2, PhiModel -> ChPTW3, XFileName -> Automatic] <> ".Gen"] ;
