QCD Corrections to the nucleon's spin structure function $G_2(x,Q^2)$

Abstract

We investigate the renormalization of the twist-3 operators which are relevant for the spin-dependent structure function $g_2(x,Q^2)$. We derive the anomalous dimension for the non-singlet part by calculating the off-shell Green's functions of the twist-3 operators including the operators which are proportional to the equation of motion.
