<div class="elementToProof">Abstract: Mapping the 3D structure of the proton in terms of its spinning quark and gluon constituents is one of the main goals of current hadronic physics investigations. Generalized parton distributions can provide part of the
solution by rendering through Fourier transformation, the spatial density of quarks and gluons with a given longitudinal momentum fraction, x. We argue that a fuller dynamical picture of the proton's interior can be captured by introducing two-body spatial
density distributions. </div>
<div class="elementToProof">Two-body densities depend on two spatial variables describing the relative particle motion and the center-of-momentum motion. They can provide therefore, additional information on the correlations in the particles' motion. </div>
<div class="elementToProof">We show that two-particle densities can be defined in QCD through double generalized parton distributions</div>
<div>and we discuss their observability in ultra peripheral collisions </div>
