This report reviews the achievements of the Crystal Barrel experiment at the Low Energy Antiproton Ring (LEAR) at CERN. During seven years of operation Crystal Barrel has collected very large statistical samples in pbarp annihilation, especially at rest and with emphasis on final states with high neutral multiplicity. The measured rates for annihilation into various two-body channels and for electromagnetic processes have been used to test simple models for the annihilation mechanism based on… 

Precision Meson Spectroscopy: Diffractive Production at COMPASS and Development of a GEM-based TPC for PANDA

The theory of the strong interaction predicts states of matter with gluonic degrees of freedom. However, they have not been observed unambiguously in experiments so far. This thesis presents a

Monte Carlo simulation of an antiproton annihilation detector system

A renewed antiproton annihilation detector system has been developed for the ATRAP (Antihydrogen Trap Collaboration) experiment at CERN (European Organization for Nuclear Research). It counts the

Production of K⁺K⁻ pairs in proton-proton collisions at 2.83 GeV

Differential and total cross sections for the pp→ppK⁺K⁻ reaction have been measured at a proton beam energy of 2.83 GeV using the COSY-ANKE magnetic spectrometer. Detailed model descriptions fitted

Pion production on exotic nuclei by antiproton annihilation

Pion production by antiproton annihilation on neutron- or proton-rich nuclei is studied in a fully quantum mechanical description of the reaction process in terms of a distorted wave approach. The

Antiprotonic-hydrogen atoms

Experimental studies of antiprotonic-hydrogen atoms have recently made great progress following the commissioning of the low-energy antiproton facility LEAR at CERN in 1983. At the same time the

Hadron physics in low-energy antiproton beams

The present state of low-energy nucleon-antinucleon physics is reviewed. Some recent experimental results, described here, cannot be explained in the standard potential models without appealing to a
