PROFILE
Subhadeep Roy
Subhadeep Roy developed and enhanced advanced data analysis features for the AliceO2Group/O2Physics repository, focusing on polarization studies and event-level physics measurements. Over three months, he introduced new C++ workflows for Lambda and anti-Lambda spin polarization analysis, refactored data structures, and improved timestamp precision by migrating to uint64_t. His work incorporated mixing parameters and kinematic matching to increase the accuracy of event processing, while also refining four-momentum calculations and boost vector applications for Lambda and Proton interactions. These contributions deepened the reliability and scalability of scientific computing pipelines, supporting more precise and maintainable particle physics analyses within the project.
