I am using the Phi program attachment of FeynCalc to try to calculate K->PiPi decays in Chiral Perturbation Theory using FeynArts to first draw the relevant topologies.
The problem comes when using 'InsertFields' to specify the particle classes because the PseudoScalar particles do not live in the standard model, as per the error message.
 I have tried generating an 'Automatic' model using vertices insertions but when executed the error message 'Tag appearance in Appearance[Lori_] is generated.

Any help on this matter would be greatly appreciated.
