✦ Synopsis

The experimental program to study nucleon structure at the 12-GeV upgraded JLab using the CLAS12 detector is presented here. The focus of this paper is on deeply virtual exclusive processes, giving access to the Generalized Parton Distributions, and semi-inclusive processes that allow extraction of Transverse Momentum Dependent distribution functions. With its wide acceptance, high luminosity, good resolution and particle identification capabilities, large Q 2 and xB coverage (1 < Q 2 < 10 GeV 2 , 0.1 < xB < 0.8), CLAS12 is the ideal facility to pursue the research on the 3-dimensional structure of the nucleon in the valence region.

• Generalized Parton Distributions (GPDs) in exclusive processes,

• Transverse Momentum Dependent (TMDs) distributions in semi-inclusive DIS,

• Parton Distribution Functions in DIS at high x B ,
