A confinement model calculation of h1(x)
V. Barone, T. Calarco, A. Drago
Abstract
The transverse polarization distribution of quarks h1(x) is computed in a confinement model, the chiral chromodielectric model. The flavor structure of h1, its Q2 evolution and Soffer's inequality are studied. The Drell--Yan double transverse asymmetry ATT is evaluated and found to be one order of magnitude smaller than the double longitudinal asymmetry.
