HepSim is a public repository with Monte Carlo simulated events for particle-collision experiments. The HepSim 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). 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.
HepSim contains event samples for physics and detector-performance 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.
HepSim Monte Carlo samples are registered by the U.S. Department of Energy Office of Scientific and Technical Information, OSTI.GOV. Each event sample is assigned a DOI (Digital Object Identifier) number as listed on the ANL-HEPSIM OSTI.GOV page. The assigned DOI numbers are also indicated on the HepSim information panel for datasets. HepSim was designed following the guidelines and principles of DOE Public Access Plan for unclassified and otherwise unrestricted scientific data in digital formats.

Physics and detector studies
Here are several links for extending this Wiki for particular detector-performance topics:
- FCC-hh detector studies - explains how to analyses data for FCC-hh detector studies
- SID detector studies - explains how to analyses data for the SiD detector (ILC)
- CEPC detector studies - shows some results with full simulations for CEPC
- EIC detector studies - shows some results with full simulations for EIC
- HCAL studies explains how to analyse ROOT data after fast detector simulations used for FCC studies
