| GLG4HitPhoton | GLG4HitPhoton stores information about a photon that makes a photoelectron in a PMT |
| GLG4HitPMT | GLG4HitPMT stores information about a PMT that detected one or more photoelectrons |
| GLG4HitPMTCollection | GLG4HitPMTCollection stores GLG4HitPMT objects |
| GLG4NeutronDiffusionAndCapture | Special process that applies simple neutron diffusion to epithermal neutrons, then calls neutron decay/capture processes "PostStepDoIt" to get decay/capture products |
| GLG4Scint | GLG4Scint is an extremely modified version of the G4Scintillation process, so much so that it's not even a G4Process anymore! Features include arbitrary scintillation light time profile and spectra, Birks' law, particle-dependent specification of all parameters, and reemission of optical photons killed by other processes |
| GLG4VertexGen_Gun | Vertex generator that can generate a primary vertex with one more particles of a given type, direction, energy, and polarization |
| GLG4VertexGen_HEPEvt | Vertex generator that generates a primary vertex based on information from an ASCII stream |
| GLG4VVertexGen | Virtual base class for vertex generators |
