G4FullEventSim

A playground application to simulate a full HepMC3 event and study the generated secondary particles.

Build Requirements

  • 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)

Usage Guide

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.
