The direct measurement of the gluon polarization in the
nucleon at the COMPASS experiment is discussed. Three complementary
analyses are considered. All of them study

based on selection of events originating from the Photon Gluon
Fusion process. Most precise preliminary value of is
obtained from the high pT pair channel for the
region:
