Measurement of the Collins and Sivers asymmetries on transversely polarised protons / COMPASS Collaboration
The Collins and Sivers asymmetries for charged hadrons produced in deeply inelastic scattering on transversely polarised protons have been extracted from the data collected in 2007 with the CERN SPS muon beam tuned at 160 GeV/c. At large values of the Bjorken x variable non-zero Collins asymmetries are observed both for positive and negative hadrons while the Sivers asymmetry for positive hadrons is slightly positive over almost all the measured x range.

Study of $\Sigma$(1385) and $\Xi$(1321) hyperon and antihyperon production in deep inelastic muon scattering / COMPASS collaboration
Large samples of $\Lambda$, $\Sigma(1385)$ and $\Xi(1321)$ hyperons produced in deep-inelastic muon scattering off a $^6$LiD target were collected with the COMPASS experimental setup at CERN. The relative yields of $\Sigma(1385)^+$, $\Sigma(1385)^-$, $\bar{\Sigma}(1385)^-$, $\bar{\Sigma}(1385)^+$, $\Xi(1321)^-$, and $\bar{\Xi}(1321)^+$ hyperons decaying into $\Lambda(\bar{\Lambda})\pi$ were measured.

The COMPASS Experiment at CERN / COMPASS Collaboration
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 more outgoing particles are detected in coincidence with the incoming muon or hadron. [...]

Observation of a $J^{PC} = 1^{-+}$ exotic resonance in diffractive dissociation of 190 GeV/c $\pi^{-}$ into $\pi^- \pi^- \pi^+$ / COMPASS collaboration
The COMPASS experiment at the CERN SPS has studied the diffractive dissociation of negative pions into the pi- pi- pi+ final state using a 190 GeV/c pion beam hitting a lead target. A partial wave analysis has been performed on a sample of 420000 events taken at values of the squared 4-momentum transfer t' between 0.1 and 1 GeV^2/c^2. [...]

The COMPASS Setup for Physics with Hadron Beams / COMPASS Collaboration
The main characteristics of the COMPASS experimental setup for physics with hadron beams are described. This setup was designed to perform exclusive measurements of processes with several charged and/or neutral particles in the final state. [...]

Azimuthal asymmetries of charged hadrons produced by high-energy muons scattered off longitudinally polarised deuterons / COMPASS Collaboration
Azimuthal asymmetries in semi-inclusive production of positive (h^+) and negative hadrons (h^-) have been measured by scattering 160 GeV muons off longitudinally polarised deuterons at CERN. The asymmetries were decomposed in several terms according to their expected modulation in the azimuthal angle phi of the outgoing hadron. [...]

Quark helicity distributions from longitudinal spin asymmetries in muon-proton and muon-deuteron scattering / COMPASS Collaboration
Double-spin asymmetries for production of charged pions and kaons in semi-inclusive deep-inelastic muon scattering have been measured by the COMPASS experiment at CERN. The data, obtained by scattering a 160 GeV muon beam off a longitudinally polarised NH_3 target, cover a range of the Bjorken variable x between 0.004 and 0.7. [...]

Exclusive $\rho^0$ muoproduction on transversely polarised protons and deuterons / COMPASS Collaboration
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 protons and deuterons. The measured asymmetry is sensitive to the nucleon helicity-flip generalised parton distributions E^q, which are related to the orbital angular momentum of quarks in the nucleon. [...]

Transverse target spin asymmetries in exclusive $\rho^0$ muoproduction / COMPASS Collaboration
Exclusive production of $\rho^0$ mesons was studied at the COMPASS experiment by scattering 160 GeV/$c$ muons off transversely polarised protons. Five single-spin and three double-spin azimuthal asymmetries were measured as a function of $Q^2$, $x_{Bj}$, or $p_{T}^{2}$. [...]

Leading order determination of the gluon polarisation from DIS events with high-$p_T$ hadron pairs / COMPASS Collaboration
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-momentum hadrons in the final state. The data were obtained by the COMPASS experiment at CERN using a 160 GeV/c polarised muon beam scattering off a polarised ^6LiD target. [...]
