The Physics Program of CLAS12

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 Q2 and xB coverage (1
