Colliding beams of high energy polarized protons at RHIC is an excellent way to probe the polarization of gluons, {anti u} and {anti d} quarks in a polarized proton. RHIC is the Relativistic Heavy Ion Collider being built now at Brookhaven in the ISABELLE tunnel. It is designed to collide gold ions on gold ions at 100 GeV/ nucleon. Its goal is to discover the quark-gluon plasma, and the first collisions are expected in March, 1999. RHIC will also make an ideal polarized proton collider with high luminosity and 250 GeV x 250 GeV collisions. The RHIC spin physics program is: (1) Use well-understood perturbative QCD probes to study non-perturbative confining dynamics in QCD. The author will measure gluon and sea quark polarization in a polarized proton, and polarization of quarks in a transversely polarized proton. (2) Look for additional surprises using the first high energy polarized proton colliders. The author will look for the expected maximal parity violation in W and Z boson production, search for parity violation in other processes, and test parton models with spin. This lecture is organized around a few of the key ideas: Siberian Snakes -- What are they? High energy proton-proton collisions are scatters of quarks and leptons. At high x, a polarized proton beam is a beam of polarized u quarks. Quark and gluon collisions are very sensitive to spin. The author discusses two reactions: how direct photon production measures gluon polarization, and how W− boson production measures u and {anti d} quark polarization.

High energy polarized beam collisions will open up the unique physics opportunities of studying spin effects in hard processes. However, the acceleration of polarized beams in circular accelerators is complicated by the numerous depolarizing spin resonances. Using a partial Siberian Snake and a rf dipole that ensure stable adiabatic spin motion during acceleration has made it possible to accelerate polarized protons to 25 GeV at the Brookhaven AGS. Full Siberian Snakes and polarimeters are being developed for RHIC to make the acceleration of polarized protons to 250 GeV possible.

This comprehensive volume covers the most recent advances in the field of spin physics, including the latest research in high energy and nuclear physics and the study of nuclear spin structure. The comprehensive coverage also includes polarized proton and electron acceleration and storage as well as polarized ion sources and targets. Many significant new results and achievements on the different topics considered at the symposium are presented in this book for the first time.

From its early beginnings at SLAC in the 1970's, the study of nucleon spin structure using polarized lepton beams and polarized nucleon targets has become increasingly important in nuclear and particle physics, with current experiments at several of the world's high energy and nuclear physics laboratories (CERN, DESY, SLAC and Jefferson Lab) and with enormous related theoretical studies. The understanding of the fascinating but complicated problem of nucleon spin structure has progressed substantially, but fundamental questions remain and it can be confidently predicted that future activity will be high.The Erice Course on The Spin Structure of the Nucleon covered both the experimental and theoretical aspects of the subject, and this volume includes the lectures given at the School. In many cases the lecture material has been extended and updated by the authors. In addition, several recent publications on experimental work have been added in an appendix.

This proceedings compiles one-page summaries and five transparencies for each talk, with the intention that the speaker should include a web location for additional information in the summary. Also, email addresses are given with the participant list. The order follows the agenda: gluon, polarimetry, accelerator, W production and quark/antiquark polarization, parity violation searches, transversity, single transverse spin, small angle elastic scattering, and the final talk on ep collisions at RHIC. The authors begin the Proceedings with the full set of transparencies from Bob Jaffe's colloquium on spin, by popular request.

In the four years since the first Trieste Meeting on Spin and Polarization Dynamics in Nuclear and Particle Physics, considerable progress has been made both in the theoretical and experimental aspects of this field. The polarization phenomena have given rise to many more detailed and crucial tests which enhance our understanding of particle physics. New information can also be uncovered in the process of conducting the various tests. For this reason, considerable efforts have been put into the present and future accelerators to extend the experimental data to measure polarization asymmetries for both polarized targets and polarized scattered and produced particles. The 2nd Adriatico Research Conference held in January 1992 brought together both theorists and experimentalists who presented many new findings. These findings have been compiled into this compact volume to give a complete picture of the wide range of theoretical and experimental problems, difficulties, results, prospects and hopes which are at the core of particle physics studies today. It will be a useful guide for the present status of polarization phenomena and their fundamental implications.

The proceedings of the 4th Italy-Japan Symposium on Heavy Ion Physics cover the following fields of nuclear physics: heavy ion nuclear reactions; nuclei under extreme conditions; nuclear astrophysics; photon detectors and physics; technology of RI beams and experimental instrumentation; application of RI beams.

Polarized beams and targets have been irreplaceable tools in nuclear and particle physics experiments for a long time and have provided us rich information on the role played by spin-degrees of freedom in the sub-nuclear world. In addition, techniques to obtain large nuclear polarization have recently been applied to new fields such as materials and medical sciences.The scope of these proceedings covers recent progress of state-of-the-art techniques in spin polarization, the cryogenic method, the atomic beam method, the optical pumping method and the nuclear reaction method.

Strangeness and Spin in Fundamental Physics is dedicated to the discussion of the role played by two subtle and somehow puzzling quantum numbers, the strangeness and the spin, in fundamental physics. They both relate to basic properties of the fundamental quantum field theories describing strong and electro-weak interactions and to their phenomenological applications. In some instances, like the partonic spin structure of the proton, they are deeply correlated. The many puzzling results recently obtained by measuring several spin asymmetries have stimulated gigantic progresses in the study of the spin structure of protons and neutrons. Intense theoretical activity has discovered new features of non-perturbative QCD, like strong correlations between the spin and the intrinsic motions of quarks inside the nucleons. The purpose of this publication is that of providing a complete, updated and critical account of the most recent and relevant discoveries in the above fields, both from the experimental and theoretical sides.
