Determination of ΔG/G from open charm events at COMPASS
Presented by Susanne KOBLITZ on 17 Apr 2007 from 11:50 to 12:10
Session: Spin Physics
Track: Spin Physics
One of the main goals of the COMPASS experiment at CERN is the determination of the gluon polarisation in the nucleon, Delta G/G. It is determined from spin asymmetries measured in the scattering of 160GeV/c polarised muons on a polarised LiD target. The gluon is accessed by the selection of photon-gluon fusion events. A selection of PGF events can be obtained with charmed mesons in the final state. Their detection is based on the reconstruction of decayed D^* and D^0 mesons in the COMPASS spectrometer. The analysis method will be discussed and the final result for Delta G/G from the open charm channel for the 2002-2004 data taking period will be presented.
