Abstract

The transverse polarization distribution of quarks $h_{1} (x)$ is computed in a confinement model, the chiral chromodielectric model. The flavor structure of $h_{1}$ , its $Q^{2}$ evolution and Soffer's inequality are studied. The Drell--Yan double transverse asymmetry $A_{T T}$ is evaluated and found to be one order of magnitude smaller than the double longitudinal asymmetry.
