A possible mechanism for spin effects in large anglep−p elastic scattering

We propose a simple parton model interpretation of large anglep?p elastic scattering in terms of elementaryq?q scattering. We formulate the model and give some numerical estimates which qualitatively explain the most important spin effects. We do not assume any particular quark recombination mechanism but we stress the importance of the proton wave function. Comparisons with other models are made.
