The `Proton Spin' Effect - Theoretical Status '97
Abstract
The theoretical status of the `proton spin' effect is reviewed. The conventional QCD parton model analysis of polarised DIS is compared with a complementary approach, the composite operator propagator-vertex (CPV) method, each of which provides its own insight into the origin of the observed suppression in the first moment of g1p. The current status of both experiment and non-perturbative calculations is summarised. The future role of semi-inclusive DIS experiments, in both the current and target fragmentation regions, is described.
