Associated Strangeness Production at COSY-TOF

The associated strangeness production in elementary reactions like pp → KYN close to reaction thresholds is one of the main topics to be investigated at the Time-of-Flight spectrometer TOF located at the Cooler Synchrotron COSY (FZ Juelich). The concept of the event reconstruction is based on the identification of the delayed hyperon and kaon decay (Λ → pπ-, Σ+ → pπ0, nπ+, and Ks0 → π+π-). Since the highly granulated detector covers almost the full phase space, all differential distributions as well as total cross sections and the hyperon polarization can be extracted from the data
