Experimental overview on GPDs and TMDs

The generalized parton distribution (GPD) functions and the transverse momentum dependent parton distribution (TMD) functions provide three-dimensional tomographies in the combined momentum-coordinate space (GPD) and the complete momentum space (TMD) of partons inside the nucleon. They uncover the rich dynamics of QCD, and provide qualitative and quantitative information about the partonic orbital angular momentum, an important piece to the solution of the proton spin puzzle. In the last ten years or so, significant progresses have been made experimentally in accessing the GPDs and TMDs. In this talk, we review the experimental progress on GPDs and TMDs and also discuss upcoming experiments in the coming decade.
