$K^-/K^+$ multiplicity ratio for kaons produced in DIS with a large fraction of the virtual photon energy / Nunes, Ana Sofia (LIP, Lisbon) /COMPASS Collaboration
For the first time, the $K^-/K^+$ multiplicity ratio is measured in deep-inelastic scattering for kaons carrying a large fraction $z$ of the virtual-photon energy. The data were obtained by the COMPASS collaboration using a 160 GeV muon beam and an isoscalar $^6$LiD target. [...]

Spin Structure of the Proton at Low $x$ and Low $Q^2$ from the COMPASS Experiment at CERN / Nunes, Ana Sofia
This thesis describes the analysis of data collected by the COMPASS experiment at CERN in 2007 and 2011, using a muon beam with 160 GeV/$c$ and 200 GeV/$c$ momenta, respectively, with the purpose of studying the process of inelastic scattering of longitudinally polarised muons off longitudinally pol [...]

First results on $A_1^p$ and $g_1^p$ at low x and low $Q^2$ from COMPASS / Nunes, Ana Sofia (LIP, Lisbon) /COMPASS Collaboration
The COMPASS experiment at CERN has collected a large sample of about 700 million events of quasi-real photoproduction in polarised m + scattering using a beam momentum of 160 GeV/ c in 2007 and 200 GeV/ c in 2011. The events have a Bjorken scaling variable in the range 4 10....

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. [...]

Odd and Even Partial Waves of $\eta\pi^-$ and $\eta'\pi^-$ in $\pi^-p\to\eta^{(\prime)}\pi^-p$ at $191\,\textrm{GeV}/c$ / COMPASS Collaboration
Exclusive production of $\eta\pi^-$ and $\eta'\pi^-$ has been studied with a $191\,\textrm{GeV}/c$ $\pi^-$ beam impinging on a hydrogen target at COMPASS (CERN). Partial-wave analyses reveal different odd/even angular momentum ($L$) characteristics in the inspected invariant mass range up to $3\,\textrm{GeV}/c^2$. [...]

Search for exclusive photoproduction of Z$_c^{\pm}$(3900) at COMPASS / COMPASS Collaboration
A search for the exclusive production of the $Z_c^{\pm}(3900)$ hadron by virtual photons has been performed in the channel $Z_c^{\pm}(3900)\rightarrow J/\psi \pi^{\pm}$. The data cover the range from 7~GeV to 19~GeV in the centre-of-mass energy of the photon-nucleon system. [...]
