Calculation of Chirality Violating Proton Structure Function h${}_1$(x) in QCD

Abstract

The twist-two chirality violating proton structure function $h_1(x)$ measurable in the polarized Drell-Yan process is calculated by means of QCD sum rules at intermediate $x$, $0.3<x<0.7$ and $Q^2\approx 5-10Ge{V}^2$.
