Abstract

Single-spin asymmetries were investigated in inclusive electroproduction of charged pions and kaons from transversely polarized protons at the Hermes experiment. The asymmetries were studied as a function of the azimuthal angle ψ about the beam direction between the target-spin direction and the hadron production plane, the transverse hadron momentum P_T relative to the direction of the incident beam, and the Feynman variable x_F. The ψ sin amplitudes are positive for π⁺ and K⁺, slightly negative forπ^- and consistent with zero for K^-, with particular P_T but weak x_F dependences. Especially large asymmetries are observed for two small subsamples of events, where also the scattered electron was recorded by the spectrometer.
