Motomi Oya developed a higher-fidelity event generation feature for the AliceO2Group/O2DPG repository, focusing on enabling and accurately modeling Pythia8 dimuon decays within the simulation workflow. By updating both C++ configuration code and INI parameters, Motomi ensured that dimuon decay channels were properly simulated, which enhances the analytic precision and reproducibility of downstream physics studies. The integration was committed as part of the Exodus workflow, reflecting a deep understanding of event generation and physics simulation. This work addressed the need for more precise particle physics modeling, leveraging expertise in C++ and simulation configuration to improve research outcomes.
