【 摘 要 】

The introduction of parton Wigner distributions in the nucleon provided us with a rigorous landscape of the different approaches to the hadron structure, linking together all possible hadronic observables. There is unfortunately as of today no known experimental process to access them. Projecting out light-cone energy and transverse momenta, a Fourier transform leads to Generalized Parton Distributions (GPDs). Those encompass Form Factors and Parton Distribution Functions, as well as a wealth of new physical informations. For instance, the Energy-Momentum tensor of partons in the nucleon can be parameterized in terms of GPDs, providing distributions of masses, angular momenta, or forces inside the nucleon.
