PROFILE
Samrangy
Samrangy Sadhu contributed to the AliceO2Group/O2Physics repository by developing and enhancing D0-hadron correlation analysis tools for high energy and particle physics research. Leveraging C++ and data analysis techniques, Samrangy integrated machine learning models to improve candidate selection and analysis precision, introducing new data structures for efficient ML score storage and inference. He implemented event-level data correlation by associating tracks and Monte Carlo particles with collision IDs, enabling more accurate heavy flavor studies. His work included refining selection logic, adding promptness and origin categorization, and correcting efficiency calculations, demonstrating a deep understanding of detector simulation and event reconstruction challenges.

Jul 1, 2025July 2025 performance summary for AliceO2Group/O2Physics focusing on D0 hadron analyses. Delivered a feature enhancement to D0 Hadron Correlation Analysis enabling separate categorization of prompt vs non-prompt D0 and hadron origins, and fixed a critical D0 selection logic to ensure only generated D0 with the correct PDG code is considered. These changes improve analysis granularity, accuracy of efficiency calculations, and overall reliability of D0-hadron studies.
