COMPASS: meson spectroscopy and low-energy meson dynamics / Friedrich, Jan M (Munich, Tech. U.) /COMPASS Collaboration
Within the broad physics programme of the COMPASS collaboration at CERN SPS, soft reactions of high-energy hadron beams on different nuclear targets are investigated. Aiming at a better understanding of the strong interaction, novel results range from tests of chiral symmetry breaking to properties of diffractively produced meson resonances studied in their multi-particle decays, such as the a1(1420) with unusual properties. [...]

Studies of light mesons at COMPASS / Uhl, Sebastian (Munich, Tech. U.) /COMPASS
To investigate the spectrum of light mesons, the COMPASS experiment has recorded data with a 190 GeV/c negative pion beam impinging on a liquid hydrogen target. Diffractive dissociation reactions at squared four-momentum transfers to the target between 0.1 and 1.0 (GeV/c)2 are studied. [...]

Light-Meson Spectroscopy at COMPASS / Krinner, Fabian (Munich, Tech. U.) /for the COMPASS collaboration
The goal of the COMPASS experiment at CERN is to study the structure and spectroscopy of hadrons. The two-stage spectrometer has large acceptance and covers a wide kinematic range for charged as well as neutral particles allowing to access a wide range of reactions. [...]

Meson Spectroscopy at COMPASS / Grube, Boris (Munich, Tech. U.) /COMPASS
The goal of the COMPASS experiment at CERN is to study the structure and dynamics of hadrons. The two-stage spectrometer used by the experiment has large acceptance and covers a wide kinematic range for charged as well as neutral particles and can therefore measure a wide range of reactions. [...]

Meson spectroscopy at VES and COMPASS / Ryabchikov, Dmitry (Serpukhov, IHEP ; Munich, Tech. U.) /VES Group ; COMPASS Collaboration
Diffractive production of $\pi^- \pi^- \pi^+$ and $\pi^- \pi^0 \pi^0$ final states is the subject of comprehensive studies performed recently by the VES and the COM-PASS experiments. COMPASS pioneered the application of novel methods of partial-wave analysis: mass-independent PWA inmultiple $(m_{3 {\pi}}, t’)$-cells, mass-dependent analysis of spin-density matrices performed simultaneously in all measured t’ bins, the analysis with freed shapes of $\pi^+ \pi^-$ isobars.

The $2\pi$ Subsystem in Diffractively Produced $\pi^-\pi^+\pi^-$ at COMPASS / Krinner, Fabian (Munich, Tech. U.) /for the COMPASS collaboration
The COMPASS experiment at CERN has collected a large dataset of $50$ million $\pi^-\pi^+\pi^-$ events produced diffractively from a proton target using a $190\,\mathrm{GeV}/c$ pion beam. The partial-wave analysis (PWA) of these high-precision data reveals previously unseen details but is limited in parts by systematic effects. [...]

Precision spectroscopy with COMPASS and the observation of a new iso-vector resonance / Paul, Stephan (Munich, Tech. U. ; Munich, Tech. U., Universe) /for the COMPASS collaboration
We report on the results of a novel partial-wave analysis based on $50\cdot 10^6$ events from the reaction $\pi^- + p \to \pi^- \pi^- \pi^+ + p_\text{recoil}$ at 190 $\text{GeV/c}$ incoming beam momentum using the COMPASS spectrometer. A separated analysis in bins of $m_{3\pi}$ and four-momentum transfer $t'$ reveals the interference of resonant and non-resonant particle production and allows their spectral separation. [...]

Hadron Physics at the COMPASS Experiment / Krinner, Fabian (Munich, Tech. U.) /for the COMPASS collaboration
Quantum Chromodynamics (QCD), the theory of strong interactions, in principle describes the interaction of quark and gluon fields. However, due to the self-coupling of the gluons, quarks and gluons are confined into hadrons and cannot exist as free particles. [...]

Strange-Meson Spectroscopy – from COMPASS to AMBER / Wallner, S. (Munich, Max Planck Inst.) /COMPASS Collaboration ; AMBER Collaboration
COMPASS is a multi-purpose fixed-target experiment at CERN's M2 beam line aimed at studying the structure and spectrum of hadrons. It has collected the so far world's largest data set on diffractive production of the $K^-\pi^-\pi^+$ final state, which in principle gives access to all strange mesons. [...]
