June 2025 monthly summary for AliceO2Group/AliceO2 focusing on enhancing the manual reject list macro to improve configurability and policy accuracy. Delivered feature to specify custom validity windows in milliseconds via JSON configuration; when not provided, the macro defaults to the run start/end times, enabling granular control without code changes. The change reduces manual intervention and supports tighter data governance.

Concise monthly summary for 2025-05 focusing on the O2Physics work stream. The primary deliverable this month is the Forward Muon Pair Analysis Enhancements (FwdMuonsUPC) in the UPC analysis workflow, implemented in AliceO2Group/O2Physics. Key code updates include new track type definitions and additional data columns, refined muon track selection criteria with MCH-MID and MFT matching, and an enhanced ZDC time/energy analysis to improve forward muon pair analysis in Ultra Peripheral Collisions.

February 2025 - O2Physics: Key delivery of Run Number Tracking for FwdMuonsUPC. Implemented RunNumber column for both dimuon and reconstructed dimuon data, propagated and stored run number during selection and reconstruction of dimuon candidates to ensure events are linked to their run. This enhances data traceability, reproducibility, and downstream analytics. Integrated with PWGUD workflow and committed as [PWGUD] Save run number information (#9738).

January 2025: Delivered enhancements to Monte Carlo truth matching in the forward muon UPC analysis within O2Physics. Standardized naming, improved data collection logic for track-to-MC particle association, and reduced log noise by refactoring non-critical messages to debug. These changes yield clearer MC truth mapping, enabling more reliable physics analyses and faster debugging downstream.

December 2024 — AliceO2Group/O2Physics: Delivered MC Dimuon Data Storage Enhancement, improving storage, analysis capabilities, and data integrity for MC dimuon workflows. Implemented data structure changes and interface updates to support richer MC dimuon information and streamlined downstream analyses.

2024-11 monthly summary for AliceO2Group/O2Physics. Delivered enhancements to the FwdMuonsUPC analysis that enable processing of both real data and MC simulations, with new data structures and histograms to store and visualize information from reconstructed and generated particles, enabling detailed comparisons and validation. Refined event selection criteria and kinematic cuts to improve analysis precision, and strengthened user-facing validation and analytics capabilities.
