A playground application to simulate a full HepMC3 event and study the generated secondary particles.
- CMake >= 3.8
- Geant4 10.7 or 11.0 with
GEANT4_USE_GDML=ON - HepMC3 (optional, but highly recommended; used to load events)
- Pythia8 (optional, for generating new events; some events are stored in the repository)
The build system compiles bin/g4FullEventSim, which expects a Geant4 macro as its first argument.
An example is given in cms2021_gg2ttbar.mac, the file gg2ttbar.dat is stored in the pythia8/ subdirectory.
