D. Deflorian et R. Sassot, NEXT-TO-LEADING ORDER QCD CORRECTIONS TO POLARIZED-LAMBDA PRODUCTION IN DIS, Nuclear physics. B, 488(1-2), 1997, pp. 367-386
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.
