Abstract: (Elsevier)
We derive target mass corrections (TMC) for the spin-dependent nucleon structure function g 1 and polarization asymmetry A 1 in collinear factorization at leading twist. The TMCs are found to be significant for g 1 at large x B , even at relatively high Q 2 values, but largely cancel in A 1 . A comparison of TMCs obtained from collinear factorization and from the operator product expansion shows that at low Q 2 the corrections drive the proton A 1 in opposite directions.- target: mass
