You did not load the generic model:
InsertFields[t11, {S[7], -S[7]} -> {S[2], S[2]}, Model -> "NMSSM"]
InsertFields[t11, {S[7], -S[7]} -> {S[2], S[2]}, Model -> "NMSSM"]
should be replaced with
InsertFields[t11, {S[7], -S[7]} -> {S[2], S[2]}, Model -> "NMSSM",GenericModel -> "NMSSM"]
InsertFields[t11, {S[7], -S[7]} -> {S[2], S[2]}, Model -> "NMSSM", GenericModel -> "NMSSM"]
The "Model"Model
option loads NMSSM.modNMSSM.mod
, the "GenericModel"GenericModel
loads NMSSM.genNMSSM.gen
.
