Debadatta Behera contributed to the AliceO2Group/O2Physics repository by developing and enhancing data analysis tools for high energy physics research. Over six months, Debadatta implemented new histogram definitions, multi-dimensional data quality monitoring, and refined event selection cuts, focusing on the PWGDQ analysis framework. Using C++ and ROOT, Debadatta expanded the HistogramLibrary to support richer correlations between physics variables, improved event filtering through custom CutLibrary logic, and modernized data pipelines for more reliable and granular analysis. The work demonstrated depth in physics software development, data analysis, and collaborative engineering, resulting in improved data quality and more robust physics analysis workflows.

Aug 1, 2025August 2025 focused on enhancing PWGDQ event filtering in O2Physics. Delivered a new event selection cut 'eventStandardSel8ppQualityNoVtxZ' to the CutLibrary, enforcing vertex quality, ITS/TPC/TOF matching, and bunch-crossing consistency to improve event filtering for PWGDQ analyses. Implemented in AliceO2Group/O2Physics with commit 35c309d7226a10c78f30d8979f7bdc4683157a52 ([PWGDQ] Updated CutLibrary.cxx (#12641)). Outcome: higher data quality, cleaner event samples, and more reliable PWGDQ workflows, enabling faster analysis turnarounds and better statistical power. Skills demonstrated: C++, CutLibrary architecture, version control, and cross-team collaboration.
