Gluon Polarisation in the Nucleon and Longitudinal Double Spin Asymmetries from Open Charm Muoproduction
COMPASS Collaboration, M. Alekseev
The gluon polarisation in the nucleon has been determined by detecting charm production via D0 meson decay to charged K and pi in polarised muon scattering off a longitudinally pol…
First results from the OSQAR photon regeneration experiment: No light shining through a wall
OSQAR Collaboration, Pierre Pugnat, Lionel Duvillaret +13
A new method to amplify the photon-axion conversions in magnetic field is proposed using a buffer gas at a specific pressure. As a first result, new bounds for mass and coupling co…
The Polarised Valence Quark Distribution from semi-inclusive DIS
COMPASS Collaboration, M. Alekseev
The semi-inclusive difference asymmetry A^{h^{+}-h^{-}} for hadrons of opposite charge has been measured by the COMPASS experiment at CERN. The data were collected in the years 200…
The COMPASS Experiment at CERN
COMPASS Collaboration, P. Abbon
The COMPASS experiment makes use of the CERN SPS high-intensitymuon and hadron beams for the investigation of the nucleon spin structure and the spectroscopy of hadrons. One or mor…
The Deuteron Spin-dependent Structure Function g1d and its First Moment
The COMPASS Collaboration, V. Yu. Alexakhin
We present a measurement of the deuteron spin-dependent structure function g1d based on the data collected by the COMPASS experiment at CERN during the years 2002-2004. The data pr…
