Previous Activities

Time Reversal Invariance at COSY (TRIC)

The TRIC project was initiated as one of the first attempts to test a fundamental symmetry at COSY. The project aims to improve the present upper limit on T-symmetry violation in the hadronic sector by at least one order of magnitude. The violation of T-symmetry is needed to explain one of the fundamental problems of the Standard Model - the Baryon Asymmetry of the Universe: where is the antimatter?

ANKE

The ANKE facility (Apparatus for Studies of Nucleon and Kaon Ejectiles) is a large acceptance forward magnetic spectrometer which was in operation at an internal target station in the COSY ring since 1998. The experimental hadron physics program at ANKE-COSY has been completed at the end of 2014.

WASA-at-COSY

WASA, a spectrometer with large solid angle acceptance, has been operated at the internal COSY beam from 2006 to 2015. It was used to investigate the production and decay of light mesons and to study symmetries and symmetry breaking patterns.

Exotic Atoms

Exotic atoms, where electron shells are replaced by a heavier negatively charged particle like muons, pions, or antiprotons, cover dimensions ranging from the atomic down to the nuclear scale. For elementary systems, e.g. pionic hydrogen, the pion-nucleon scattering lengths are directly accessible by means of X-ray spectrocsopy.
