QCD, the Parton Model, and the Nucleon Polarised Structure Functions}
Abstract
The present talk summarises the 1993 situation in understanding the spin structure of the nucleon via electron and muon polarised deep--inelastic scattering (PDIS). The central question I shall address here is if the data can be interpreted as evidence for polarisation in the ``strange'' nucleon ``sea'', and I conclude that they can not: incidentally, I also find that they can not be constructed as evidence for violation of perturbative QCD (PQCD), either. Talk presented at ``Quinto Convegno su Problemi di Fisica Nucleare Teorica'', Cortona (Arezzo, Italy), October 1993. To be published in the proceedings: ``Perspectives on Theoretical Nuclear Physics (V)'', L. Bracci, et al., eds. (ETS Ed., Pisa 1994)
