Single target-spin asymmetry in semi-inclusive deep inelastic scattering on a transversely polarized nucleon target
We use a new set of Collins functions to update a previous prediction on the azimuthal asymmetries of pion production in a semi-inclusive deep-inelastic scattering process on a transversely polarized nucleon target. We find that the calculated results can give a good explanation to the HERMES experiment with the new …
