Resumen:
The complete next to leading logarithmic [O(αs)] corrections to the spin-dependent weak deep inelastic structure functions g1, g3, and g4 are calculated using dimensional regularization within the HVBM method. Analyzing the quark- and gluon-initiated contributions to these corrections for different values for the quark masses, a consistent factorization prescription for spin-dependent quark distributions, which safely removes soft contributions, is defined. It is shown that within this scheme, quark-initiated corrections are comparable in magnitude to those of gluonic origin, even though their contributions to the moments are small.
