Factorization in semi-inclusive polarized deep inelastic scattering

We calculate and analyze the O ( α s ) one-particle inclusive cross section in polarized deep inelastic lepton-hadron scattering, using dimensional regularization and the HVBM prescription for γ 5. We discuss the factorization of all the collinear singularities related to the process, particularly t...

Summary:We calculate and analyze the O ( α s ) one-particle inclusive cross section in polarized deep inelastic lepton-hadron scattering, using dimensional regularization and the HVBM prescription for γ 5. 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 scheme and in another one, called MS p , which factorizes soft contributions and guarantees the axial current (non-) conservation properties.
