Recent Results of Semi-inclusive DIS Experiments at Jefferson Lab
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 or 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 experimental halls at JLab with 6 GeV electron beam using both polarized or upolarized beam and target combinations. The kinematic range was mainly focued on valence quark region. In this proceeding we will discuss some of the recent results from JLab 6 GeV run.
