Developed and integrated a Bertini Photonuclear Interaction Model into the SimCore library within the LDMX-Software/ldmx-sw repository, focusing on enhancing simulation realism for targeted particle production studies. The implementation leveraged C++ and Geant4 simulation frameworks to enable exact N-hard-particle photonuclear event generation, incorporating PDG ID filtering and energy-threshold selection for precise control over event topology. This feature allows users to simulate scenarios with specific particle types and energies, supporting advanced physics modeling requirements. The work demonstrated depth in both physics modeling and software engineering, with all changes tracked and prepared for review through a dedicated commit and pull request process.
