Erratum to: "Nuclear Effects on R=σ_L/σ_T in Deep-Inelastic Scattering" Phys.Lett. B475(2000)386
HERMES Collaboration, A. Airapetian
This erratum revokes the main conclusion of a Letter that reported measurements of cross sections for deep-inelastic scattering (DIS) of leptons on He and N targets, exp…
Measurement of Longitudinal Spin Transfer to Lambda Hyperons in Deep-Inelastic Lepton Scattering
HERMES Collaboration, A. Airapetian
Spin transfer in deep-inelastic Lambda electroproduction has been studied with the HERMES detector using the 27.6 GeV polarized positron beam in the HERA storage ring. For an avera…
Observation of a Single-Spin Azimuthal Asymmetry in Semi-Inclusive Pion Electro-Production
A. Airapetian
Single-spin asymmetries for semi-inclusive pion production in deep-inelastic scattering have been measured for the first time. A significant target-spin asymmetry of the distributi…
