The Correlated Spatial Structure of the Proton: Two-body densities as a framework for dynamical imaging

We present results on two-parton densities in coordinate space, which capture a fuller dynamical picture of the proton’s internal structure, including information on the relative position between quarks and gluons in the transverse plane. The connection of such two body densities to observables proceeds in QCD via the definition of double generalized parton distributions.
