Description
The quark-gluon dynamics manifests itself in a set of non-perturbative functions describing all possible spin-spin and spin-orbit correlations. Single and Dihadron semi-inclusive and hard exclusive production, both in current and target fragmentation regions, provide a variety of spin and azimuthal angle dependent observables, sensitive to the dynamics of quark-gluon interactions. Studies of evolution properties of observables in SIDIS, and validation of the existing theory, is a challenging task, which will require high precision measurements in multidimensional bins.
In this talk, we present an overview of the current status and some planned measurements of the orbital structure of nucleons at JLab, and possible extensions to future physics program of upgraded to 20-24 GeV JLab .
