The COMPASS Collaboration
The COMPASS experiment at the CERN SPS has studied the diffractive dissociation of negative pions into the π−π−π+ final state using a 190 GeV/c pion beam hitting a lead target. A partial waveExpand
Potential use of Rare Earth Oxides as Tracers for Soil Erosion and Aggregation Studies
Sediment delivery from small watersheds or eroMost existing soil loss data are spatially-averaged, though various sion plots has been well monitored. These data are tracing techniques have been usedExpand
Construction, test and commissioning of the triple-gem tracking detector for compass
The Small Area Tracking system of the COMPASS experiment at CERN includes a set of 20 large area, fast position-sensitive Gas Electron Multiplier detectors, designed to reliably operate in the harshExpand
Using Rare-Earth Oxide Tracers for Studying Soil Erosion Dynamics
Spatially averaged soil erosion data provide little information on soil erosion dynamics. Dynamically varied, spatially distributed erosion data are needed to better understand erosion processes andExpand
Measurement of azimuthal hadron asymmetries in semi-inclusive deep inelastic scattering off unpolarised nucleons
Abstract Spin-averaged asymmetries in the azimuthal distributions of positive and negative hadrons produced in deep inelastic scattering were measured using the CERN SPS longitudinally polarised muonExpand
Collins and Sivers asymmetries in muonproduction of pions and kaons off transversely polarised protons
Measurements of the Collins and Sivers asymmetries for charged pions and charged and neutral kaons produced in semi-inclusive deep-inelastic scattering of high energy muons off transversely polarisedExpand
Hadron transverse momentum distributions in muon deep inelastic scattering at 160 GeV/c
Multiplicities of charged hadrons produced in deep inelastic muon scattering off a 6LiD target have been measured as a function of the DIS variables xBj, Q2, W2 and the final state hadron variablesExpand
Leading and Next-to-Leading Order Gluon Polarization in the Nucleon and Longitudinal Double Spin Asymmetries from Open Charm Muoproduction
The gluon polarisation in the nucleon was measured using open charmproduction by scattering 160 GeV/c polarised muons off longitudinally polarisedprotons or deuterons. The data were taken by theExpand
The Spin Structure Function g p 1 of the Proton and a Test of the Bjorken Sum Rule The COMPASS Collaboration
New results for the double spin asymmetry A1 and the proton longitudinal spin structure function g p 1 are presented. They were obtained by the COMPASS collaboration using polarised 200 GeV muonsExpand
