The QUAntum chromodynamics Nuclear TOMography (QuantOm) Collaboration convenes domain scientists, applied mathematicians, and computational scientists to address the challenge of 3D imaging of quarks and gluons in nucleons and nuclei.
QuantOm is developing a unique event-level inference framework to obtain a quark and gluon tomography of nucleons and nuclei using high-energy scattering data. This event-level approach stands to have a transformational impact on the data analysis workflow that connects theory with experimentation. The resulting quark and gluon tomography will help ensure that current and future facilities, such as Jefferson Lab and the Electron-Ion Collider planned at Brookhaven National Laboratory, deliver on their scientific mission to reveal the inner structure of the visible universe at the femtometer scale.

Illustration of the two types of processes that occur in lepton-nucleus collisions. The left panel is a semi-inclusive
process where the nucleus is destroyed. The right panel is an exclusive process were the nucleus remains intact.
Tomographic images for quarks and gluons in a nucleus. The left images give their spatial structure, provided by exclusive processes, while the images on the right give their momentum structure, provided by semi-inclusive processes.
