Overview

1. 5x41 GeV
2. 10x100 GeV
3. 10x130 GeV

Each configuration has multiple files (indexed 001-200) with 5000 events per file.

A two-step plan for file processing. To better isolate any potential issues as there too many changes (new software, updated generator, new energy level, etc.).

For all processing, the latest stable EIC container: 25.07-stable.

1. Reprocess the existing Monte Carlo files with the new 25.07-stable container. I.e. usual generator data with the latest reconstruction.

2. Process new 10 million event files, with new energy

Campaign 2025-05

Overview

The Campaign 2025-05 run to make data current with EIC EPIC software updates.

The campaign includes simulations with three beam energy configurations:

1. 5x41 GeV
2. 10x100 GeV
3. 18x275 GeV

Each configuration has multiple files (indexed 001-200) with 5000 events per file.

timestamp: '2025-06-04T12:05:06.867483'
input_file: /volatile/eic/romanov/meson-structure-2025-06/eg-hepmc/*.hepmc
container_image: /cvmfs/singularity.opensciencegrid.org/eicweb/eic_xl:nightly

Data Location

The campaign data is stored in the following locations (on JLab farm):

• HEPMC files:
  /volatile/eic/romanov/meson-structure-2025-03/eg-hepmc
• reco info: /volatile/eic/romanov/meson-structure-2025-06/reco

Campaign 2025-03

Overview

The Campaign 2025-03 is focused on testing the new ZDC lambda reconstruction algorithm using the latest ePIC software. This campaign reuses meson-structure-2025-02, reusing some of the existing hepmc files while implementing improved reconstruction techniques.

Processing Details

The campaign uses a processing pipeline that converts Monte Carlo event generator files to a format suitable for full detector simulation and reconstruction:

1. MCEG files are converted to HEPMC format (splitting large files into manageable chunks)
2. The HEPMC files are processed through the latest ePIC reconstruction software
3. Output files include both EDM4EIC format and histogram files

Data Location

The campaign data is stored in the following locations:

• HEPMC files:
  /volatile/eic/romanov/meson-structure-2025-03/eg-hepmc

  Note: These are linked from the previous campaign:

  /volatile/eic/romanov/meson-structure-2025-02/eg-hepmc

• Reconstruction output:
  /volatile/eic/romanov/meson-structure-2025-03/reco

Processing Commands

The exact commands used in this campaign:

# Original MCEG files location
