Polarised parton distributions

High Energy Physics - Phenomenology 2009-10-28 v1

Abstract

We analyze spin dependent parton distributions consistent with the most recent measurements of the spin dependent deep inelastic scattering structure functions and obtained in the framework of the spin dilution model. Predictions for the doubly polarised proton-proton Drell-Yan asymmetry, for the high pTp_{T} photon production mechanism and J/ΨJ/\Psi excitation are calculated using these distributions and are shown to be particularly adequate to unveil the polarisation of partons in the proton.
