Abstract
Determining of the gluon polarisation in the nucleon, by measurement of the double spin asymmetry of the photon-gluon fusion process is the main goal of the COMPASS experiment at CERN. Experiment uses 160 GeV polarized muon beam and polarised 6LiD target. Photon-gluon fusion events are selected using charmed mesons and hadron pairs at large pT. Preliminary results on charm signal extraction, and spin asymmetry Aγ∗d of the cross sections for high pT hadron pairs production are presented.
