Abstract
A first evaluation of the polarized valence quark distribution from the COMPASS experiment (CERN/SPS) is presented. The data were collected by COMPASS in the years 2002--2004 using a 160 GeV polarized muon beam scattered off a large polarized LiD target and cover the range GeV and . The analysis is based on the difference asymmetry, , for hadrons of opposite charges, which gives a direct access to the polarization of valence quarks.
