We have carried out a phenomenological analysis of the latest deep
virtual Compton scattering experimental data based on the generalized
parton distribution formalism. This allows us to extract the dependence
of the spatial size of the proton on the quark’s longitudinal momentum.
This results in the first continuous two-dimensional momentum-space
image and tomography of the proton based on experimental data.
