“Toward Quantum Imaging of Nuclei”
The atomic nucleus emerges from interacting quantum particles called quarks and gluons, but how this happens remains unknown. This might be elucidated with quantum-level “images” of their position, orbital motion, spin alignment, and entanglement. I will describe recent and upcoming experiments at Jefferson Laboratory that use a high-intensity, high-energy electron beam to probe a wide range of nuclear targets, from polarized lithium to lead. I will also explain how these studies pave the way for future research at the Electron-Ion Collider (EIC), which will usher in a new era by providing a novel tool: particle jets. To advance EIC jet physics, we are developing next-generation, highly granular calorimeter systems, which can be enhanced with state-of-the-art AI/ML methodologies. I will summarize recent prototype testing conducted at various facilities and discuss plans for further testing and construction in the near future.
