SM background MC available for the 2024r-pp Run 3

ATLAS Datasets
1

Hi,

I am working with the ATLAS Open Data 2024r-pp release for a research project using the atlasopenmagic I have a few questions:

  1. Could you confirm that the MC samples available in the 2024r-pp release via atlasopenmagic contain only BSM signal samples (Z’, W’, graviton, etc.) and no SM background MC (Z+jets, W+jets, tt̄, QCD multijet)?

  2. Is there SM background MC available for Run 3 pp collision data anywhere in the ATLAS Open Data releases? If so, which release name or CERN record ID should I use to access it?

  3. The 2024r-pp release metadata lists 374 datasets with DSIDs in the 301xxx range (e.g. 301204, 301209). Are these all BSM signal samples, and are there plans to release SM background MC for Run 3?

  4. When parsing the 2024r-pp data files, I observe files with _mc_ in their filenames (DSIDs 37xxxxxx range). Could you clarify what physics processes these correspond to?

Thank you for your time and support.
