January 2025 performance summary for uhh-cms/cmsdb and columnflow/columnflow. Focused on strengthening EWK data modeling, cross-energy cross-section accuracy, and calibration robustness to deliver higher-quality analyses with reduced manual intervention. Delivered key feature improvements for EWK process definitions and jet-bin categorization, ensured unique process IDs, and hardened Egamma calibration logic to gracefully handle optional inputs while maintaining MC-context gating. These changes enhance data integrity, analysis efficiency, and cross-energy consistency across 13 TeV and 13.6 TeV datasets.

December 2024 (Month: 2024-12) – Summary of work in uhh-cms/cmsdb. Key features delivered include consolidated Higgs analysis dataset configurations for nanoAOD v14 in 2023 preBPix, covering single-Higgs channels (ggF, VBF, VH, W±H, ttH), triple-H (hhh_4b2tau), and hh->bbtautau with varying couplings (kl, kt, c2) across ggF and VBF. Implemented dedicated nanoAOD v14 pipelines for these analyses. Major bugs fixed include linting fixes for preBPix nanoAOD v14 Python scripts (newline terminations) to satisfy style checks without altering functionality. Commits associated with features: 42cfa2b2f0bf40bccc0a3b83ae40fdff26989fe2; 0643e1c82a3f0eb42a88467e99477b8b39e442ce; c086e29835efb192a33d3a58daab1c08dea3ec75; lint fix: 809b5cf8a65f672193a2939649693707149422be. Overall impact includes standardized dataset configurations, improved reproducibility and maintainability, and reduced setup time for multi-channel Higgs analyses. Technologies/skills demonstrated include nanoAOD v14 customization, Python scripting, linting and code quality, multi-channel physics data configurations, and version control collaboration in cmsdb. Business value: faster analytics readiness, reduced configuration drift, clearer audit trail.
