Worked on the AliceO2Group/O2DPG repository to expand physics simulation capabilities by adding psi(2S) and Upsilon particles to decay tables and event generation workflows. This involved updating data configuration files and modifying C++ code, specifically enhancing decaytable_LMee.dat and GeneratorEMCocktailV2.C to support more realistic modeling of heavy quarkonium channels. The approach focused on data-driven configuration and integration with ROOT-based simulation tools, ensuring improved fidelity for downstream physics analyses. No major bugs were reported during this period, and the work emphasized collaborative, version-controlled development practices while prioritizing validation and integration testing to maintain workflow reliability and scientific accuracy.
