PROFILE

Mingze Li

Over a three-month period, contributed to the AliceO2Group/O2Physics repository by developing and optimizing data analysis frameworks for high energy physics studies. Built a derived-data framework for D* → D0 π decays, introducing new data structures and selection logic to streamline candidate reconstruction and analysis. Enhanced Monte Carlo simulation workflows by refactoring analysis logic for D*+ mesons in PbPb collisions, adding centrality-aware features and improving data access efficiency. Further extended the analysis pipeline by implementing a centrality axis for polarisation studies, enabling more accurate cross-scenario comparisons. Work demonstrated strong C++ development, scientific computing, and collaborative integration within complex physics software.

March 2026: Delivered Centrality Axis for Polarisation Studies in O2Physics, adding a centrality-dependent output to improve D*+ polarisation analyses across collision scenarios. This enables more accurate physics interpretations and cross-scenario comparisons. No critical bugs reported this month; feature deployed with minimal disruption. Co-authored commit 41e7a843d3485877fa00981e121a7a1b9827be70 with ALICE Action Bot; demonstrates collaborative development and code quality. Overall impact: enhanced data analysis fidelity, extended PWGHF output capabilities, and stronger support for polarisation-based physics programs. Technologies demonstrated: C++/ROOT analysis, PWGHF workflow integration, and Git-based collaboration.

July 2025 — AliceO2Group/O2Physics: Delivered centrality-aware MC analysis for D*+ mesons in PbPb collisions. This included refactoring MC analysis logic in PWGHF to improve efficiency, adding centrality-dependent analysis, enhancing the handling/association of MC-generated particles with centrality information, and streamlining data structures for MC collision data to support more detailed analyses. The work is anchored by the commit f74d7154eecc7c24de4298afb5318d13736546cd ([PWGHF] Optimise and update the logic for MC analysis (#11921)). Impact: higher analysis throughput and precision for PbPb studies, enabling more accurate physics conclusions and faster iteration. Technologies/skills: C++/ROOT in PWGHF, MC analysis optimization, data-structure refactoring, centrality handling.
