First measurement of the gluon polarisation in the nucleon using D mesons at COMPASS
… measurements it is <br>possible to determine the gluon density in the nucleon with good accuracy via <br>a so-called QCD fit. <br>In the case of the spin structure of the nucleon the situation is different. Even after decades of experimental and theoretical efforts it remains to be understood how …

Determination of the gluon polarisation in the nucleon using hadron pairs with high transverse momentum at COMPASS
… has been measured, the contributions from gluons and orbital angular momentum are not constrained. <br> <br>This thesis is dedicated to the determination of the gluon polarisation in the nucleon. The analysis is based on the data taken by the COMPASS experiment at CERN during the years 2002 …
