Valence quark helisity distribution from COMPASS
The evaluation of the polarized valence quark distribution $\Delta u_{v}(x) +\Delta d_{v}(x)$ from the COMPASS experiment (CERN/SPS) is presented. The analysis is based on the "difference asymmetry", $A^{h^{+}-h^{-}} (x)$, for hadrons of opposite charges. The data were collected in the yea...
