TL;DR: In this paper, a measurement for the production of the anti-hydrogen atom H0 ≡ pe+, the simplest atomic bound state of antimatter, has been presented, which is well suited for investigations of fundamental CPT violation studies under different forces.

TL;DR: In this paper, the reaction p → K + Λp was measured exclusively at the cooler synchrotron COSY at beam momenta of p Beam = 2.50 ± 0.75 ǫ 2.75 g/c using the TOF detector.

TL;DR: In this paper, the authors studied hyperon production in the threshold region in the reaction pp → K + Λ p using the time-of-flight spectrometer COSY-TOF.

TL;DR: In this article, the reaction pp → ppη was measured at excess energies of 15 and 41 MeV at an external target of the Julich Cooler Synchrotron COSY with the time-of-flight spectrometer.

TL;DR: In this paper, the two-pion production reaction pp → ppπ+π− was measured with a polarized proton beam at T p ≥ 750 and 800MeV using the short version of the COSY-TOF spectrometer.
