Inclusive and semi-inclusive asymmetries at COMPASS

We present preliminary results for the measurement of the inclusive asymmetry, A1 d, and semi-inclusive asymmetries for positive and negative hadrons, A~t and A~i. These asymmetries will be used to determine contributions of quarks andanti-quarks to the nucleon spin. Data obtained by scattering polarized muons of 160 GeV off a polarized 6 LiD target are presented. The analysis is based on data collected in years 2002 and 2003. The covered kinematic range is Q 2 > 1GeV 2 and 0.004 < xBj < 0.7.
