DOIAbstract
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 <math altimg="si1.gif" xmlns="http://www.w3.org/1998/Math/MathML"><msub><mrow><mi>P</mi></mrow><mrow><mi>T</mi></mrow></msub></math> relative to the direction of the incident beam, and the Feynman variable <math altimg="si2.gif" xmlns="http://www.w3.org/1998/Math/MathML"><msub><mrow><mi>x</mi></mrow><mrow><mi>F</mi></mrow></msub></math> .
