摘要：

We calculate and analyze the O(alpha(s)) one-particle inclusive cross section in polarized deep inelastic lepton-hadron scattering, using dimensional regularization and the HVBM prescription for ys We discuss the factorization of all the collinear singularities related to the process, particularly those that are absorbed in the redefinition of the spin-dependent analogue of the recently introduced fracture functions, This is done in the usual <(MS)over bar> scheme and in another one, called <(MS(p))over bar>, which factorizes soft contributions and guarantees the axial current (non-)conservation properties.
