Subject:	THE SPIN STRUCTURE OF THE NUCLEON: a phenomenological introduction and the most recent results
Speaker:	Franco Bradamante Trieste University and INFN, Trieste Italy
Date:	Friday, May 18, 2012
Time:	11:00 A.M.
Place:	CEBAF Center Auditorium
Abstract:	After a short historical introduction on the understanding of the structure of the proton and of the neutron, the investigation of the spin structure of the nucleon via semi- inclusive deep inelastic scattering on polarized nucleons is updated with the most recent results of the Jefferson LAB, HERMES, and COMPASS experiments. A short description is given of these experiments, which are complementary in phase space and use sophisticated and different techniques to polarize the nucleon targets. The cases of target spin parallel or orthogonal to the direction of the incoming lepton require different experimental techniques, have a different phenomenology and need a different theoretical treatment. After reviewing these differences, the most recent transverse spin advances are presented, and evidence is given that new properties of matter at the partonic level have been discovered.
