The transverse polarized structure function in DIS and chiral symmetry breaking in QCD

Abstract

We study the polarized structure functions in QCD. We show that $g_T$ which probes helicity flip interactions in hadrons on the light-front indeed measures the QCD dynamics of chiral symmetry breaking. The relation between chiral symmetry breaking and the observed $g_2$ data is explored.
