Description
Summary:(HERMES Collaboration) Results obtained by the HERMES Collaboration for the polarized parton distributions u, d, , , s extracted from inclusive and semi-inclusive asymmetries on H and D in a LO analysis are presented. The up and down distributions are measured with good precision and are determined to be positive and negative respectively. The sea distributions have been extracted for the first time and the strange sea is consistent with zero within errors.Single spin asymmetries on transversely polarized hydrogen target provide evidence of transversity distributions.
