PROFILE
Mingze Li
Mingze Li contributed to the AliceO2Group/O2Physics repository by enhancing spin and polarisation analysis workflows for PbPb collisions, focusing on Dstar and Charm studies. Using C++ and data analysis techniques, Mingze implemented event-plane based calculations for Dstar spin alignment and refactored code to support direct collision iteration and flexible Q-vector handling. He addressed data quality by fixing mass assignment errors and extending Monte Carlo data columns, and improved centrality filtering robustness by correcting loop control logic. Additionally, Mingze resolved histogram configuration issues in event-plane analyses, ensuring accurate data representation and supporting reproducible, maintainable physics analysis pipelines.

Aug 1, 2025Performance review for 2025-08: Delivered a robustness fix for centrality filtering in O2Physics, significantly improving stability and data quality in centrality-based selections. Addressed a loop-control bug in taskCharmPolarisation.cxx by replacing an erroneous 'return' with 'continue', ensuring collisions outside the centrality range are skipped rather than exiting the function prematurely. The change is tracked in commit 5589eaba8c3a813861cb5f02541b128850d2dcb2 and PR #12743. This fix reduces edge-case failures, enhances analytics reliability, and shortens debugging cycles. Skills demonstrated include C++ debugging, rigorous code review, and regression-friendly changes with clear traceability to a single repository.
