Low-energy experiments find a nucleon size of around 0.5 femtometer (fm), or about 5x10-16 meters. Heavy ion collisions provide a fundamentally different perspective on the nucleon size compared to these low-energy experiments. Previous analyses of heavy ion experimental data have found a much larger nucleon …
