- EIC
- Electron-Ion Collider
- ddsim
- The DD4hep command-line driver for Geant4 detector simulations, including a built-in particle gun.
- npsim
-
A thin layer on top of
ddsimwith ePIC-specific options (such as Cerenkov and optical photon physics) pre-configured. Recommended for almost all regular ePIC simulations. - eic-shell
- The EIC standard software environment, a singularity/apptainer or docker container with a curated selection of software components used for EIC simulations and analysis.
- EDM4hep
-
The common event data model used to store ePIC simulation output in ROOT
files (
.edm4hep.root). - HepMC3
- The event-record format used to exchange generator-level events (e.g. from Pythia8) as input to simulation.
