The Monte Carlo files (truth level, fast simulations and full simulations) can be accessed from the HepSim repository link. Currently these studies are based on Jas4pp data-analysis environment. Geometry files for full detector simulations can be found in the detector repository.

You have several choices for data analysis:

• Using the hs-tools package as described in short description. It is designed for downloading files and processing truth-level files using Python/Jython scripts (or using Java)
• Using Jas4pp. It is similar to the above package, but it has packages needed to process full-simulation samples (SLCIO files).
• Using C++/ROOT. If you run over ProMC (truth-level) files, look at the manual ProMC manual. If you run over ROOT files from Delphes, use Delphes manual. If you analyse LCIO files with full simulation, look at LCIO manual.

Some analysis examples implemented in Python and C++ can be found in here. Also look for specific topics given below.

Every entry in the HepSim has “truth-level” files (created by Monte Carlo generators) and reconstruction tags: Data after processing by the fast simulation program (Delphes) have the tag “rfastNNN” (NNN is a number), while data after full simulation have the tag “rfullNNN” (NNN is a number). The info pages for each sample has the link to the tag and the information page describing the detector.

If you need to find all samples for a given tag, use the search page. Then type the tag name. For example, if you are searching for the “rfull006” reconstruction tag, this page returns a complete list of Monte Carlo samples which were processed for a given detector.

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

Currently these studies are based on Jas4pp data-analysis environment. Geometry files for full detector simulations can be found in the detector repository.

This manual describes how to work with truth-level samples posted on HepSim. HepSim Python/Java analysis page explains how to write code to read truth-level files using Python on the Java platform.
