Factorization in semi-inclusive polarized deep inelastic scattering

We calculate and analyze the (script O sign)(αs) one-particle inclusive cross section in polarized deep inelastic lepton-hadron scattering, using dimensional regularization and the HVBM prescription for γ5. We discuss the factorization of all the collinear singularities related to the process, parti...
