New results on $\Delta G/G$ from COMPASS

The gluon polarisation, $\Delta g/g$, is determined from photon-gluon fusion (PGF) events produced in scattering of 160 GeV polarised muons off polarised deuterons. Two independent methods based on LO QCD are used to extract PGF events: selection of $D$ or $D^{*}$ mesons or a pair of high $p_{t}$ hadrons. In the former we use the data collected in 2002-2004 and 2006 and apply a new method of the signal strength parametrisation. In the latter we select $Q^{2} >$ 1 GeV$^{2}$ region from 2002-2004 data and apply a new method of accounting for background processes.
