Abstract
The investigation of the partonic degrees of freedom beyond collinear approximation (3D description) has been gained increasing interest in the last decade. The Thomas Jefferson National Laboratory, after the CEBAF upgrade to 12 GeV, will become the most complete facility for the investigation of the hadron structure in the valence region by scattering of polarized electron off various polarized nucleon targets. A compendium of the planned experiments is here presented.
Highlights
Since decades, few questions challenge the interpretation of hadron structure and phenomena in Hadronic Physics in terms of perturbative QCD
X denotes the longitudinal momentum fraction carried by the partons and the scale (Q2) dependence has been neglected for simplicity
At the same time new channels of investigation have been gained importance as the study of semi-inclusive deep-inelastic scattering (SIDIS) where at least one final state hadron is detected in coincidence with the scattered lepton
Summary
Few questions challenge the interpretation of hadron structure and phenomena in Hadronic Physics in terms of perturbative QCD. Besides allowing to access transversity in conjunction with the Collins fragmentation function, SIDIS experiments open the way to the extraction of transverse-momentum-dependent (TMD) parton distributions [2].
