In March 2026, delivered a focused enhancement in AliceO2Group/O2Physics to improve data analysis reliability by strengthening event selection for mixed events and refining Monte Carlo histogram categorization for generated particles. This work closes gaps in mixed-event handling and optimizes MC label bins, enabling more accurate, reproducible analyses for high-energy physics experiments.

February 2026: Delivered resonance analysis enhancements and a streamlined data processing workflow in O2Physics. Implemented support for k*0 resonance analysis, added a centrality estimator for phitask, and introduced a dedicated kstar analysis task. Also performed a targeted refactor of event selection and processing logic to improve maintainability and throughput. These changes strengthen physics output potential, improve centrality-based analyses, and accelerate insights for resonance studies. Commit references: [PWGLF] Refactor event selection and processing logic (#15185); [PWGLF] Added centrality estimator for phitask and new separate kstar task (#15197).

In August 2025, delivered configurable Track QA, DCA-inclusive acceptance filter, and TH3F-based MC histograms for Lambda analyses in AliceO2Group/O2Physics. These changes broaden QA coverage, enhance analysis fidelity, and improve Lambda MC histograms for more precise physics studies.

July 2025 monthly summary: Delivered core physics analysis enhancements for Lambda(1520) resonance across pp and OO collisions, expanded histogram configurability, and strengthened robustness with QA/MC improvements and a rotational background estimation workflow. Added Lambda1520 PDG code to PhysicsConstants to enable accurate simulations. These efforts improve analysis accuracy, configurability, reproducibility, and readiness for physics results.
