SEMINAR      Tuesday, 28 September 2004 - h. 15:00  Aula Seminari (A34)     S. White (BNL and The Rockfeller Univ.) Recent results on inelastic diffraction in Au-Au, d-Au and pp collisions at RHIC Abstract Like the future LHC collider, RHIC is a combined function machine, which provides collisions of Heavy Ions as well as protons. Unlike the LHC, the experiments at RHIC were completely designed with the goals of Heavy Ion physics in mind and subsequently used parasitically also for the study of spin structure of the proton. Common goals for event characterization (centrality of collisions, reaction plane, etc.) have lead to instrumentation, which is now yielding results in inelastic diffraction of Heavy ions as well as protons. I will review recent results on “rapidity gap” physics including both photon and pomeron exchange processes and discuss opportunities in this field at the LHC.
