LATEST RESULTS FROM SMC

    Abstract:

    The inclusive measurements of the Spin Muon Collaboration (SMC) with a special focus on the preliminary '96 results are presented. The SMC performed the polarized DIS experiment with the highest beam energy and is therefore the best suited one to study the polarized structure functions at low x, the kinematic region under investigation in this workshop. For Q2 > 1 GeV2 the x-region down to x = 0.003 can be explored. By dropping the low Q2 cut the x-region can be extended to x = 0.0008. This data play an essential role in estimating the high energy contribution to the DHG integral, which turns out not to be better constraint than to 20 - 40 % of the total prediction. At low x, the requirement of an observed hadron in the final state is an efficient tool to select DIS events. Preliminary results for the '96 data with a significant reduction of the statistical error (up to 40 %) using hadron tagged events are presented.
