Worked on enhancing the AliceO2Group/O2DPG repository by enabling high-fidelity dimuon decay event generation within the Pythia8 simulation workflow. Focused on accurate modeling, the developer updated both C++ configuration files and INI parameters to support and fine-tune dimuon decay processes, integrating these changes as part of the Exodus workflow. This work improved the analytic precision and reproducibility of downstream physics studies by ensuring more realistic simulation of dimuon channels. Leveraging skills in event generation, particle physics, and physics simulation, the developer contributed a targeted feature that addressed validation risks and advanced the repository’s simulation capabilities for physics research.
