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.
