Investigation of single spin asymmetries in pi^{+} electroproduction
arXiv:hep-ph/0010261 · doi:10.1016/S0375-9474(00)00609-6
Abstract
The azimuthal single target-spin asymmetries for pi^{+} production in semi-inclusive deep inelastic scattering of leptons off longitudinally polarized protons are evaluated using two main approaches available in the literature. It is shown that the approximation where the twist-2 transverse quark spin distribution in the longitudinally polarized nucleon is small enough to be neglected leads to a consistent description of all existing asymmetries observed by the HERMES experiment.
