11 SIDDHARTA The determination of the isospin dependent
SIlicon Drift Detector for Hadronic Atom Research by Timing Applications The determination of the isospin dependent KN scattering lengths through a ~ precision measurement of the shift and of the width of the Ka line of kaonic hydrogen and the first measurement of kaonic deuterium Measuring the KN scattering lengths with the precision of a few percent will drastically change the present status of low-energy KN phenomenology and provide a clear assessment of the SU(3) chiral effective Lagrangian approach to low energy hadron interactions.

20 HALL B Physics Program (see M. Radici’s Talk)
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.
