The 3D pictures of the nucleon: status and prospects

We propose an overview of the nucleon tomography in both mixed position-momentum space and pure momentum space. Three-dimensional pictures of the nucleon congregate a lot of information on Quantum ChromoDynamics in its non-perturbative regime, in particular about how the partons are distributed inside the nucleon and how initial and final-state interactions affect the system. After a short presentation of how such information can be accessed experimentally, we present selected recent developments and results. The last part of the presentation will be devoted to prospects.
