Description
Generalized Transverse Momentum Dependent (GTMD) distributions provide the most complete information on the structure of hadrons one can hope to constrain via experiments described in perturbative QCD. Using their Fourier transforms, Wigner distributions, it is possible to write very intuitive definitions for some physical properties inside hadrons such as the decomposition of its spin between its constituent helicities and orbital angular momenta.
In this talk we will first discuss the theoretical definition, properties and limits of GTMD distributions. Then we will consider the prospects for phenomenology where these distributions are involved, and what we can learn about GTMDs in different processes.
