Description
Semi-inclusive deep inelastic scattering (SIDIS) is a powerful tool to explore the 3-d structure of nucleon in momentum space. Through a combination of polarized/unpolarized lepton beam and nucleon target one can study various transverse-momentum dependent parton distribution functions (TMDs) that appear in the SIDIS cross-section. TMDs provide a description of nucleon structure in terms of parton's transverse momentum and its transverse spin, which enables us to study the quark orbital angular momentum effects in the nucleon. Several SIDIS experiments were performed in three Halls at Jefferson Lab with 6 GeV electron beam using both polarized/upolarized beam and target combinations. The kinematic range was mainly focued on valence quark region. We will present some recent results from Jefferson Lab 6 GeV run and discuss future plans after the 12 GeV upgrade.
