Abstract

Single-spin asymmetries have been measured for semi-inclusive electroproduction of pi /sup +/, pi /sup -/, pi /sup 0/ and K/sup +/ mesons in deep-inelastic scattering off a longitudinally polarised deuterium target. The asymmetries appear in the distribution of the hadrons in the azimuthal angle phi around the virtual photon direction, relative to the lepton scattering plane. The corresponding analysing powers in the sin phi moment of the cross section are 0.012+or-0.002(stat.)+or-0.002(syst.) for pi /sup +/, 0.006+or-0.003(stat.)+or-0.002(syst.) for pi /sup -/, 0.021+or-0.005(stat.)+or-0.003(syst.) for pi /sup 0/ and 0.013+or-0.006(stat.)+or-0.003(syst.) for K/sup +/ The sin 2 phi moments are compatible with zero for all particles.
