Abstract
We perform a detailed study of the consistency between different
sets of
polarized
deep inelastic scattering data and theory, from the standpoint
of a next to
leading order QCD
global analysis, and following the criteria proposed by Collins
and Pumplin. In
face
of recent suggestions that challenge the usual assumption about
parent parton
spin
independence of unpolarized fragmentation functions, we specially
focus on
polarized
semi-inclusive data.
