Nous considérons un modèle que nous avons développé précédemment pour décrire les asymétries spin-spin dans la diffusion p-p à grands angles et nous l'appliquons pour prédire les asymétries spin-spin du proton dans la diffusion e-p. Nos résultats diffèrent de ceux attendus dans le schéma de la QCD perturbative. La mesure des asymétries de spin fournirait une mesure directe des deux facteurs de forme élastiques du proton et un test clair des différents mécanismes. Nous commentons d'autres effets de spin.We consider a model previously developed to describe spin-spin asymmetries in proton-proton large angle elastic scattering and apply it to predict proton spin-spin asymmetries in electron-proton elastic scattering.
