Abstract

The JLab 12 GeV upgrade with a proposed solenoid detector and the CLAS12 detector can provide the granularity and three-dimensional kinematic coverage in longitudinal and transverse momentum, 0.1x0.50.1\le x \le 0.5, 0.3z0.70.3 \le z \le 0.7 with PT1.5GeVP_T \le 1.5 {\rm GeV} to precisely measure the leading twist chiral-odd and TT-odd quark distribution and fragmentation functions in SIDIS. The large xx experimental reach of these detectors with a 12 GeV CEBAF at JLab makes it {\em ideal} to obtain precise data on the {\em valence-dominated} transversity distribution function and to access the tensor charge.
