Abstract

Single-spin asymmetries have been measured for semi-inclusive electroproduction of π⁺, π^-, π⁰ and K⁺ mesons in deep-inelastic scattering off a longitudinally polarised deuterium target. The asymmetries appear in the distribution of the hadrons in the azimuthal angle φ around the virtual photon direction, relative to the lepton scattering plane. The corresponding analysing powers in the sin φ moment of the cross section are 0.012 ± 0.002(stat.) ± 0.002(syst.) for π⁺, 0.006±0.003(stat.)±0.002(syst.) for π^-, 0.021±0.005(stat.)±0.003(syst.) for π⁰ and 0.013±0.006(stat.)±0.003(syst.) for K⁺. The sin 2φ moments are compatible with zero for all particles.

AB - Single-spin asymmetries have been measured for semi-inclusive electroproduction of π+, π-, π0 and K+ mesons in deep-inelastic scattering off a longitudinally polarised deuterium target. The asymmetries appear in the distribution of the hadrons in the azimuthal angle φ around the virtual photon direction, relative to the lepton scattering plane. The corresponding analysing powers in the sin φ moment of the cross section are 0.012 ± 0.002(stat.) ± 0.002(syst.) for π+, 0.006±0.003(stat.)±0.002(syst.) for π-, 0.021±0.005(stat.)±0.003(syst.) for π0 and 0.013±0.006(stat.)±0.003(syst.) for K+. The sin 2φ moments are compatible with zero for all particles.
