Description

Unraveling the rich structure of hadrons requires studying its quark and gluon degrees of freedom including their transverse momenta and the origin of the proton spin in terms of the spin and orbital angular momenta of its constituents. To that end, a large number of experiments have been carried out over the past four decades at accelerator laboratories in the United States, Europe and Japan. Data related to transverse-momentum dependent (TMD) PDFs allow the study of spin-orbit correlations inside the nucleon and the mapping of its transverse-momentum structure, while hard exclusive data related to generalized parton distributions (GPDs) open the pathway to the 3D nucleon structure in position space. An overview of experimental results will be given with emphasis on the fixed-target experiments.
