Nous discutons le modèle QCD pour la diffusion dure et ses prédictions pour les éléments de matrice densité de spin du méson vecteur (V) dans la réaction à grands p[MATH] γp → VX. Les résultats peuvent constituer un test du schéma probabiliste sous-jacent au modèle QCD parton et des interactions élémentaires et aussi bien une façon de mieux comprendre la dépendance en spin du processus de fragmentation des quarks et des gluons. Nous discutons aussi la réaction e+e- → VX dans la région d'interférence γ-Z.QCD hard scattering model predictions for the vector meson (V) spin density matrix elements in the large pT process γp → VX are discussed. These results can be a test of both the underlying probabilistic scheme of the QCD parton model and of...
