Longitudinal spin structure at compass

Y. Bedfer (on behalf of the COMPASS collaboration) ; CEA/IRFU, Saclay, France

Abstract

COMPASS is a fixed-target experiment at CERN's Super-Proton-Synchrotron. Part of its physics program is dedicated to the spin structure of the nucleon, which it studies with a 160 GeV polarized muon beam and polarized targets. An overview of its measurements performed with longitudinal target polarization is given. In particular, recent results, concerning the gluon polarization, the separation of the contributions of the individual quark flavors and the test of the Bjorken sum rule, are presented.

Keywords

nucleon spin structure; longitudinal target polarization; polarized 160 GeV muon beam; gluon polarization; Bjorken sum rule
