Gluon polarisation from high transverse momentum hadron pairs production (COMPASS)
A new preliminary result of a gluon polarisation $\Delta G/G$ obtained selecting high transverse momentum hadron pairs in DIS events with $Q^2>1 \ ({GeV/}c)^2$ is presented. Data has been collected by COMPASS at CERN during the 2002-2004 years. In the extraction of $\Delta G/G$ contributions comi...

| description | A new preliminary result of a gluon polarisation $\Delta G/G$ obtained selecting high transverse momentum hadron pairs in DIS events with $Q^2>1 \ ({GeV/}c)^2$ is presented. Data has been collected by COMPASS at CERN during the 2002-2004 years. In the extraction of $\Delta G/G$ contributions coming from the leading order $\gamma q$ and QCD processes are taken into account. A new weighting method based on a neural network approach is used. Also a preliminary result of $\Delta G/G$ for events with $Q^2<1 \ ({GeV/}c)^2$ is presented. |
