HepSim is a public repository with Monte Carlo simulated events for high-energy physics (HEP) 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) with the goal to create references to truth-level MC records for current and future experiments.

Event data samples are createdusing:

• BlueGene/Q supercomputer of the Argonne Leadership Computing Facility (with BG@HEPlib library)
• Open-science grid (OSG) and OSG CI Connect (“FutureColliders” project).
• 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

Monte Carlo events are generated using the BlueGene/Q supercomputer of the Argonne Leadership Computing Facility (BG@HepLib library), ANL-HEP cluster, ATLAS Connect virtual cluster service, OSG (Open Science Grid) Connect and NERSC. The file storages for this project are provided by ATLAS Connect, NERSC science gateways and by ANL HEP.

The Monte Carlo files (truth-level, fast and Gean4-based simulations) can be accessed from the HepSim repository link.

• 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
