Transverse Spin: HERMES Results and Future Plans

Abstract

Results from the HERMES experiment are presented on single-spin asymmetries in semi-inclusive hadron production from longitudinally polarized targets. The data are compared with a number of theoretical calculations which relate the azimuthal dependence of the asymmetries to the transversity structure function h_1(x).Comment: 9 pages, 4 figures requiring 9 EPS files, contribution to the European Workshop On The QCD Structure Of The Nucleon (QCD-N'02), to be published in Nucl.
