The recently approved COMPASS experiment attempts a measurement of the gluon polarization around η ![]()
der=0 SRC=/images/glyphs/BQ2.GIF> 0.1 with a precision of δ(Δg/g) ![]()
der=0 SRC=/images/glyphs/BQ2.GIF> 0.1. The experiment uses open charm muo-production and large PT hadron pairs to tag the photon-gluon fusion process. COMPASS will also cover a rich spin-physics program in polarized DIS.
