Single target-spin asymmetries in semi-inclusive pion electroproduction on longitudinally polarized protons

We evaluate the single-spin sinΦ h and sin2 Φ h azimuthal asymmetries in the semi-inclusive pion production in deep inelastic lepton scattering off longitudinally polarized proton target in the HERMES kinematics. A good agreement with the HERMES data is a achieved using only the twist-2 distribution...

Description
Summary:We evaluate the single-spin sinΦ h and sin2 Φ h azimuthal asymmetries in the semi-inclusive pion production in deep inelastic lepton scattering off longitudinally polarized proton target in the HERMES kinematics. A good agreement with the HERMES data is a achieved using only the twist-2 distribution and fragmentation functions.
