What version of GEANT4 are you using? I am not sure whether we have any models which _produce_ heavy mesons. We do support, in some models (not BERT), heavy mesons as beam particles (for example, to model how a B produced at the LHC would interact with the beampipe and vertex detector).

The FTF and QGS models are for high-energy interactions, and "should" be able to produce heavy mesons. I do not know for sure if they are configured to pop c-cbar or b-bbar pairs as part of the high-energy evolution.
