1pm - 2pm: What do protons and neutrons look like?

Nucleons are particularly complex and interesting bound systems that combine both relativistic and quantum features. We propose a brief overview of how the spatial structure of nucleons (and other hadrons) is currently investigated. While electromagnetic form factors have long been studied and allow us to map the spatial distribution of electric charge and magnetization within nucleons, the past decade has seen a particular surge of interest in so-called gravitational form factors. These now make it possible to map the distributions of energy, momentum, and pressure, shedding new light on the origins and nature of mass, angular momentum, and mechanical properties of hadrons. It is for these reasons that these new form factors have, for example, become key elements of the experimental program of the future Electron-Ion Collider (EIC) in the US.
