3DStructure of the Nucleon

In recent years, the hadronic physics community has extended its
investigation of partonic structure of hadrons beyond the standard
parton distribution functions (PDFs), by exploring the parton's motion
and its spatial distribution in the direction perpendicular to the
parent hadron's momentum. Two sets of non-perturbative functions have
been introduced to investigate and describe the structure of hadrons at
the quark-gluon level: Transverse Momentum Dependent (TMD) parton
distributions and Generalized Parton Distributions (GPDs).Much of the
interest in TMDs and GPDs has been triggered by their potential to
help unravel the spin structure of the nucleon, as they carry
information not only on the longitudinal but also on thetransverse
momentum and position of partons, providing rich and direct
informationon the orbital motion of quarks.Studies of the 3D PDFs are
currently driving the upgrades of several existing facilities (JLab and
RHIC), and the design and construction of new facilities worldwide
(EIC,FAIR, and JPARC).
In this talk, we present an overview of the latest developments in
studies of the orbital structure of nucleons and nuclei as well as some
future measurements at various facilities worldwide.
