CLAS12

The primary goal of experiments using the  CLAS12 detector at energies up to 12 GeV is the study of the internal nucleon dynamics by accessing the nucleon's transverse momentum (TMD's) and generalized (GPD's) parton distributions functions.

Towards this end, the detector has been tuned for studies of exclusive and semi-inclusive reactions in a wide kinematic range.
