The observed asymmetries are used to study the extraction of the polarized structure function g_5 and the polarized parton distributions $Δu$ and $Δd$ in the proton.9 pages, 4 figures, Contributed paper to the Proceedings of the Workshop on Physics at HERA with Polarized Protons and ElectronsHigh Energy Physics - PhenomenologyA study on Delta u and Delta d in charged current events using polarized beams at HERAtext
