Measurement of radiative widths of $a_2(1320)$ and $\pi_2(1670)$ / COMPASS Collaboration
The COMPASS Collaboration at CERN has investigated the reaction $\pi^- \gamma \rightarrow \pi^-\pi^-\pi^+$ embedded in the Primakoff reaction of $190~\textrm{GeV}$ pions scattering in the Coulomb field of a lead target, $\pi^- \text{Pb} \rightarrow \pi^-\pi^-\pi^+ \text{Pb}$. Exchange of quasi-real photons is selected by isolating the sharp Coulomb peak observed at momentum transfer below $0.001~(\text{GeV}/c)^2$. [...]

A measurement of the azimuthal asymmetry in dihadron production in deep-inelastic scattering of muons on transversely polarised proton (NH$_{3}$) targets are presented. They provide independent access to the transversity distribution functions through the measurement of the Collins asymmetry in single hadron production. [...]

Measurement of azimuthal hadron asymmetries in semi-inclusive deep inelastic scattering off unpolarised nucleons / COMPASS Collaboration
Spin-averaged asymmetries in the azimuthal distributions of positive and negative hadrons produced in deep inelastic scattering were measured using the CERN SPS muon beam at $160$ GeV/c and a $^6$LiD target. The amplitudes of the three azimuthal modulations $\cos\phi_h$, $\cos2\phi_h$ and $\sin\phi_h$ were obtained binning the data separately in each of the relevant kinematic variables $x$, $z$ or $p_T^{\,h}$ and binning in a three-dimensional grid of these three variables.

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 $p_{T}^{2}$. [...]

Hadron Transverse Momentum Distributions in Muon Deep Inelastic Scattering at 160 GeV/$c$ / COMPASS Collaboration
Multiplicities of charged hadrons produced in deep inelastic muon scattering off a $^6$LiD target have been measured as a function of the DIS variables $x_{Bj}$, $Q^2$, $W^2$ and the final state hadron variables $p_T$ and $z$. The $p_T^2$ distributions are fitted with a single exponential function at low values of $p_T^2$ to determine the dependence of $\langle p_T^2 \rangle$ on $x_{Bj}$, $Q^2$, $W^2$ and $z$. [...]

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 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 were taken by the COMPASS collaboration between 2002 and 2007. [...]

D* and D Meson Production in Muon Nucleon Interactions at 160 GeV/c / COMPASS Collaboration
The production of D* and D mesons in inelastic scattering of 160 GeV/c muons off a $^6$LiD target has been investigated with the COMPASS spectrometer at CERN for 0.003 (GeV/c)$^2 < Q^2 < 10$ (GeV/c)$^2$ and 3x10$^-5< x_{Bj}$ < 0.1. The study is based on 8100 events where a $D^0$ or anti $D^0$ is detected subsequently to a $D^{*+}$ or $D^{*-}$ decay, and on 34000 events, where only a $D^0$ or anti $D^0$ is detected. [...]

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. [...]

Measurement of the Cross Section for High-$p_T$ Hadron Production in Scattering of 160 GeV/c Muons off Nucleons / COMPASS Collaboration
The cross section for production of charged hadrons with high transverse momenta in scattering of 160 GeV/c muons off nucleons at low photon virtualities has been measured at the COMPASS experiment at CERN. The results, which cover transverse momenta from 1.1 to 3.6 GeV/c, are compared to a next-to-leading order perturbative Quantum Chromodynamics (NLO pQCD) calculation in order to evaluate the applicability of pQCD to this process in the kinematic domain of the experiment.
