HepSim is a public repository with Monte Carlo simulations for particle-collision experiments. It contains predictions from leading-order (LO) parton shower models, next-to-leading order (NLO) and NLO with matched parton showers. It also includes Monte Carlo events after fast ("parametric") and full (Geant4) detector simulations and event reconstruction.

The HepSim Monte Carlo event repository was started at ANL during the US long-term planning study of the American Physical Society’s Division of Particles and Fields (Snowmass 2013). HepSim contains event samples for physics and detector-performace studies for High-Luminosity LHC (HL-LHC), International Linear Collider (ILC), Very Large Hadron Collider (VLHC), Future Circular Collider (FCC-ee and FCC-hh), Compact Linear Collider (CLIC), Circular Electron-Positron Collider (CEPC), Electron-Ion Collider (EIC) and other future particle colliders.

Event samples of the HepSim repository were created using:

BlueGene/Q supercomputer of the Argonne Leadership Computing Facility (with BG@HEPlib library)
Open-science grid (OSG) and OSG CI Connect ("FutureColliders" and "EIC" projects)
ATLAS Connect virtual cluster service ("ATLAS CI" project)
Argonne’s Laboratory Computing Resource Center (LCRC) ("HepSim" project)
ATLAS Analysis support (ASC) cluster at HEP/ANL

The file storage is provided by:

STASH2 storage at OSG CI Connect
FAXBOX storage at ATLAS Connect
Science gateways at NERSC
MC.HEP server at ASC ANL
EIC SIM at JLAB

HepSim was designed following the guidelines and principles of DOE Public Access Plan for unclassified and otherwise unrestricted scientific data in digital formats.
