Summary of Experimental Data on High Energy Spin Physics

Abstract

High Energy Spin Physics has made significant progress. During a very short period a set of new phenomena have been established — relevant to the spin structure of the nucleons, hyperon polarization, the single- and double-spin asymmetries. The recent advent of the polarized proton and antiproton beams, and unpolarized Σ - beam opened a new avenue for study of spin physics at high energy, like the flavor dependence of the spin effect, the spin transfer mechanism, the comparative study of the hyperon polarization and analyzing power, etc. These and other news in High Energy Spin Physics are discussed in this review.
