Title: Study of 3D partonic structure of nucleon with SoLID at JLab Abstract: Semi-inclusive Deep Inelastic Scattering (SIDIS) is powerful tool to study 3-d structure of nucleon in the momentum space. Using an electron beam and polarized/unpolarized 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 have been proposed at Jefferson Lab that plan to use the upgraded 11 GeV beam and polarized/unpolarized nucleon targets. In this talk I will describe our recent studies for the future precision experiments at JLab using polarized proton/helium-3 targets and the proposed Solenoidal Large Intensity Device (SoLID) in Hall A. These experiments will cover a wide range of kinematics in all four dimensions (x,Q^2,p_T,z) which is very crucial for extracting TMDs.
