PROFILE
Yazhenlin
Yalin contributed to the AliceO2Group/O2Physics repository by developing and enhancing analysis modules for high energy and particle physics data. Over three months, Yalin extended strangeness correlation analysis to Pb-Pb collisions, implementing new configurations and selection criteria in C++ to align with existing pp workflows and improve data filtering reliability. He delivered comprehensive energy correlator analysis features, expanding histogram support and refactoring analysis variables to streamline code maintainability. Yalin also introduced advanced configuration options, random phi transformations, and transverse-range parameters, increasing the robustness and flexibility of physics analyses. His work demonstrated depth in C++ development, data analysis, and scientific computing.
