Abstract

The proton is the most abundant constituent of visible matter in the universe. Starting with the early work of Hofstadter, measurements of hard electron scattering reactions have continuously advanced our understanding of the proton’s structure, leading to the current interpretation in terms of many-body QCD. While remarkable progress has been made, the proton’s three-dimensional structure and the origin of its emergent properties, such as spin and mass remain poorly understood.

Building on recent theoretical advances, a new family of deeply virtual exclusive scattering processes (DVEP) has been proposed to directly probe the QCD energy-momentum tensor, with the aim of gaining new insights into the structure and properties of the proton within the context of the strong interaction.

In this talk, I will present results from our studies of DVEP processes, which provide, for the first time, determinations of previously inaccessible observables related to proton structure. I will focus on new results from the CLAS12 experiment at Jefferson Lab in the valence quark regime, and I will also discuss the evolution of this program over a much broader kinematic regime at the future Electron-Ion Collider, currently under development at Brookhaven National Laboratory.
