Measurement of the Gluon Contribution to the Nucleon Spin at COMPASS
The measurement of the gluon contribution to the nucleon spin ΔG is one of the main goals of the COMPASS experiment located at the CERN Super Proton Synchrotron. The key reaction is the photon gluon fusion to D (D̄) ‐mesons. The status of the analysis of the D 0‐ and D *‐events is shown as well as t...

| Sumario: | The measurement of the gluon contribution to the nucleon spin ΔG is one of the main goals of the COMPASS experiment located at the CERN Super Proton Synchrotron. The key reaction is the photon gluon fusion to D (D̄) ‐mesons. The status of the analysis of the D 0‐ and D *‐events is shown as well as the expected statistical error of ΔG/G from the first 3 years of data taking |
