# Target mass corrections and twist-3 in the nucleon spin structure functions - High Energy Physics - Phenomenology

Abstract: The Nachtmann moment is employed to study the contribution of twist-3operator to the nucleon spin structure functions. Target mass corrections tothe Cornwall-Norton moments of the spin structure functions $g {1,2}$ arediscussed. It is found that the corrections play a sizeable role to thecontribution of the twist-3 $\tilde d 2$ extracted from the Cornwall-Nortonmoments.
