Leading and Next-to-Leading Order Gluon Polarisation in the Nucleon and Longitudinal Double Spin Asymmetries from Open Charm Muoproduction
C. Adolph, M. G. Alekseev, V. Yu. Alexakhin +217
The gluon polarisation in the nucleon was measured using open charm production by scattering 160 GeV/c polarised muons off longitudinally polarised protons or deuterons. The data w…
D* and D Meson Production in Muon Nucleon Interactions at 160 GeV/c
C. Adolph, M. G. Alekseev, V. Yu. Alexakhin +217
The production of D* and D mesons in inelastic scattering of 160 GeV/c muons off a ^6LiD target has been investigated with the COMPASS spectrometer at CERN for 0.003 (GeV/c)^2 < Q^…
Exclusive rho^0 muoproduction on transversely polarised protons and deuterons
C. Adolph, M. G. Alekseev, V. Yu. Alexakhin +217
The transverse target spin azimuthal asymmetry A_UT in hard exclusive production of rho^0 mesons was measured at COMPASS by scattering 160 GeV/c muons off transversely polarised pr…

Leading order determination of the gluon polarisation from DIS events with high-p_T hadron pairs
C. Adolph, M. G. Alekseev, V. Yu. Alexakhin +212
We present a determination of the gluon polarisation Delta g/g in the nucleon, based on the longitudinal double-spin asymmetry of DIS events with a pair of large transverse-momentu…
