NEW EXPERIMENTAL RESULTS FOR INTERMEDIATE- AND HIGH-ENERGY POLARIZATION ASYMMETRY

Abstract

We review recent experimental data on polarization asymmetry at intermediate and high energies. We include phenomenological interpretations of the data. In this review we examine the present status of polarization physics at intermediate and high energies. Special attention is directed to controversial experimental results as well as interpretations of the data. Our objective is to contribute toward the planning of future experimental facilities and experiments. For more detailed description and discussion of various experiments and phenomenological interpretations, we provide extensive references. Polarized-beam programs at the SLC (Stanford Linear Collider), HERA (Hadron Electron Ring Accelerator, and EPC (Electron Positron Collider) are not included in this review. Neither do we discuss the technologies of polarized ion sources, polarized targets, polarized beams, or accelerators.
