NEXT-TO-LEADING ORDER QCD CORRECTIONS TO POLARIZED-LAMBDA PRODUCTION IN DIS

We calculate next to leading order QCD corrections to semi-inclusive p olarized deep inelastic scattering and e(+)e(-) annihilation cross sec tions for processes where the polarization of the identified final-sta te hadron can also be determined. Using dimensional regularization and the HVBM prescription for the ys matrix, we compute corrections for d ifferent spin-dependent observables, both in the <(MS)over bar> and <( MS)over bar (p)> factorization schemes, and analyse their structure. I n addition to the well-known corrections to polarized parton distribut ions, we also present those for final-state polarized fracture functio ns and polarized fragmentation functions, in a consistent factorizatio n scheme.
