Pull request overview
This PR updates Run 3 configuration and analysis code to align processes, datasets, and global settings with the correct Run 2022–2024 productions, and introduces a configurable low-mass dimuon cut in the analysis baseline.
Changes:
- Reorganizes DY, EWK, Higgs, TT/ST/TW/TTX, and data processes across Run3 2022/2022EE/2023/2023BPix/2024, including new EWK 2μ2j and detailed VBF/ggH/VH/TTH signal processes, and updates
phys_models.yamlaccordingly. - Extends dataset catalogs for these eras with the appropriate NanoAOD/MiniAOD campaign paths, adds generator and cross-section metadata, and wires new data-taking periods.
- Adds
nano_versionand related globals to Run 3global.yamlfiles, switches the jet-veto logic to use it, and introducesLowerMassCutin the baseline to enforce an m(μμ) > 45 GeV selection at the RDataFrame level.

Comments suppressed due to low confidence (2)
config/Run3_2023BPix/datasets.yaml:1
- As in the 2024 config, the
generatorstring for all VBFH amc@nlo samples is misspelled asamcanlo; this should be corrected toamcatnloso that generator-based logic and metadata remain consistent across eras.
#### DY samples ####
AnaProd/anaTupleDef.py:1
- Using
global_params["nano_version"]assumes every configuration defines this key; to avoidKeyErrorwhen running on configs that have not yet been updated (e.g. older eras), it would be safer to access this with a default (or handle its absence) and/or documentnano_versionas a required field in allglobal.yamlfiles.

This PR is intended because I realized that in Run2024 config the data processes were the 2022 ones
