The medium-energy nuclear experimental program planned by the Ohio University group aims to answer the questions: “How does subatomic matter organize itself inside a proton or neutron?” and “Are the fundamental interactions relating to the structure of proton or neutron fully understood?” These research areas were framed as outstanding challenges to modern physics in the 2023 Long Range Plan for Nuclear Science. The PI’s research focuses on studying the internal structure of protons and neutrons. The strong force, one of Nature’s four fundamental forces, governs this internal structure. The PIs will also investigate the limits of our understanding of Nature’s fundamental forces by seeking physics beyond the Standard Model of particle physics. They will work with an electron beam colliding with hydrogen, deuterium, and other nuclear targets at the Thomas Jefferson National Accelerator Facility (JLab). Principal Investigators Roche and King, three graduate students, and one undergraduate stu- dent, will perform the research supported by this award. The program has multifold broader impacts, including training the next generation of scientists and engaging the public through STEM education for High School students. The Ohio group will analyze the data from the JLab NPS-RG1A experiment, which completed data taking in the Spring of 2024, and contribute to the study of the internal structure of the nucleon using the Generalized Parton Distribution framework. In addition, the gro
