Target mass corrections and twist-3 in the nucleon spin structure functions
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 are
discussed. It is found that the corrections play a sizeable role to the
contribution of the twist-3 extracted from the Cornwall-Norton
moments.Comment: 11 pages, 1 figure
