description

New results on the longitudinal inclusive spin asymmetry A 1 d in the range 1 Q 2 100  (GeV/c) 2 and 0.004 x 0.7 are presented. From these results we derive the spin-dependent structure function g 1 d which we include in a QCD analysis of the world data. The data were obtained by the COMPASS experiment at CERN using a 160 GeV polarized muon beam scattered off a large polarized 6 LiD target. The results are in agreement with those from previous experiments and improve considerably the statistical accuracy in the region 0.004 x 0.03 .
