On the twist-3 contribution to h_L in the instanton vacuum
B. Dressler🇩🇪 · M.V. Polyakov🇩🇪
Abstract
We show that the instanton model of the QCD vacuum indicates the parametric smallness of the twist-3 contributions to the polarized structure function h_L. This smallness is related to the diluteness of the QCD instanton vacuum.
