Developed Dalitz-decay Monte Carlo simulation configurations for the AliceO2Group/O2DPG repository, enabling more realistic modeling of proton-proton collisions at 13.6 TeV using Pythia8. Focused on expanding simulation capabilities for Dalitz decays, the work involved implementing new C++-based configuration files and establishing validation checks to ensure the quality of generated data. Added test configurations to streamline future analyses and reduce downstream validation effort. The approach emphasized data integrity and reproducibility, supporting upcoming particle physics studies. Demonstrated skills in C++ programming, Monte Carlo simulations, and particle physics, with all contributions centered on feature delivery and collaborative version control practices.
