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 created using:

• BlueGene/Q supercomputer of the Argonne Leadership Computing Facility (BG@HepLib library)
• OSG (Open Science Grid) 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
• NERSC science gateways
• MC.HEP server at ASC ANL

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

Here are several links to 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
