Description

An overview of recent COMPASS (NA58/SPS) results on the determination of longitudinal polarized quark distributions is given. The results were obtained in inclusive and semi-inclusive deep-inelastic scattering of a 160 GeV polarized muon beam off a large polarized ${}^6$LiD target. The covered kinematics range is $0.004<x<0.7$ and $1<Q2<100$ (GeV/$c)2$. The presented data were collected by COMPASS in the years 2002--2004. A projection of the statistical precision for the data collected on deuterons from the same ${}^6$LiD target in 2006 and on protons from NH${}_3$ target in 2007 is presented.
