Target mass corrections and twist-3 in the nucleon spin structure functions

Abstract

The Nachtmann moment is employed to study the contribution of twist-3 operator to the nucleon spin structure functions. Target mass corrections to the Cornwall-Norton moments of the spin structure functions $g_{1,2}$ are discussed. It is found that the corrections play a sizeable role to the contribution of the twist-3 ${\tilde{d}}_2$ extracted from the Cornwall-Norton moments.
