In June 2025, Eric Chenard developed and integrated a Bertini Photonuclear Interaction Model into the SimCore library within the LDMX-Software/ldmx-sw repository. His work focused on enabling simulation of photonuclear events that produce exactly N hard particles, filtered by PDG ID and energy threshold, supporting targeted particle production studies with enhanced physics realism. Using C++, Geant4 simulation, and Python, Eric implemented event selection logic that allows researchers to specify both the number and type of particles generated in each event. This feature addressed the need for precise control in simulation scenarios, reflecting a deep understanding of physics modeling and software integration.
