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.
