✦ Synopsis

COMPASS has measured the incoherent exclusive electroproduction of ρ 0 over a wide Q 2 range and at < W >= 10 GeV. Spin density matrix elements were extracted from the angular distribution. Preliminary results of the analysis of the data taken in 2002 presented here are consistent with a substantial increase of R = σ L /σ T with Q 2 and a weak violation of SCHC, in agreement with other high energy experiments. θ cos -

The COMPASS spectrometer was designed for the NA58 fixed-target experiment at the CERN SPS. The physics aim is the study of the spin structure of the nucleon and the spectroscopy of hadrons with muon and hadron beams. Several novel techniques like Micromegas, GEMs and straw tracking detectors were d

An important goal of the COMPASS experiment is the study of semi-inclusive polarised muon scattering from a polarised target. The identification of the hadrons will allow, for the first time, a direct measurement of the gluon polarisation AG/G from the cross-section asymmetry of open charm productio

The recently approved COMPASS experiment attempts a measurement of the gluon polarization around r/\_\_ 0.1 with a precision of 5(Ag/g) ,,o 0.1. The experiment uses open charm muo-production and large PT ha&on pairs to tag the photon-gluon fusion process. COMPASS will also cover a rich spin-physics
