Hi, Geant4 knows to deal "only" with ordinary particles (observed ones). I almost SUSY ignorant, so please forgive the obvious questions below. Are R-hadrons stable ? If so, then the particle-matter interactions for such particles would need to be implemented. That would be quite a work. Presumably, this will depend on the model(s), and as such, Geant4 can not provide the variety of models. If they are unstable, with a lifetime that would not allow the particle to reach the first detector elements, then this would correspond to the typical use case of a generator, that will take care to decay the R-hadron, according to SUSY physics, into ordinary particles, that will be passed for tracking to Geant4. For such generators, CMS experts will certainly help.
