PROFILE
Samrangy
Over five months, contributed to the AliceO2Group/O2Physics repository by developing and refining features for D0-hadron correlation analysis in high energy and particle physics. Leveraging C++ and data analysis techniques, integrated machine learning models to improve candidate selection and incorporated efficiency corrections directly into analysis pipelines. Enhanced event-level data correlation by associating tracks and Monte Carlo particles with collision identifiers, and introduced efficiency weighting within histogramming routines. Addressed analysis granularity by enabling prompt versus non-prompt categorization and corrected selection logic for D0 particles. The work demonstrated a methodical approach to software development, focusing on accuracy, maintainability, and physics-driven requirements.

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.
