Cterrevo
Cristina Terrevoli contributed to the AliceO2Group/O2Physics repository by developing and refining data analysis workflows for high energy and particle physics. She enhanced DStar and Xic candidate selection processes, implementing advanced invariant mass calculations and dual-detector PID logic to improve signal purity and data integrity. Using C++ and leveraging her expertise in data processing and software engineering, Cristina fixed critical bugs, introduced QA-driven monitoring, and streamlined histogram management. Her work included refactoring analysis modules for maintainability and machine learning readiness, replacing hard-coded values with constants and simplifying data flows, which improved reproducibility and established a robust foundation for future analyses.

Jun 1, 2025June 2025 monthly summary for AliceO2Group/O2Physics focused on code quality improvements and ML-readiness. Delivered a code cleanup and refactor of Xic analysis and HfTaskXic to remove PID track tables, replace magic numbers with constants, reorganize member variables, and update signatures to use aod::TracksWDca. Streamlined ML-oriented data processing by removing unnecessary MC prong acceptance checks and simplifying histogram/data filling logic. These changes establish a cleaner foundation for ML workflows, reduce technical debt, and improve maintainability and reproducibility of physics analyses.
