Early data on $K^-$ induced reactions off protons are collected and used in a coupled-channel partial wave analysis (PWA). Data which had been published in the form of Legendre coefficients are included in the PWA. In a {it primary} fit using 3* and 4* resonances only, we observe some significant discrepancies with the data. In a systematic search for new $Lambda$ and $Sigma$ hyperon resonances, additional candidates are found. The significance of the known and of the additional resonances is evaluated. Seventeen resonances listed with 1* or 2* and one resonance listed with 3* in the Review of Particle Properties cannot be confirmed, five new hyperons are suggested. The partial-wave amplitudes deduced in this analysis are compared to those from other analyses.
Indications for the production of a neutral excited hyperon in the reaction pp -> p K^+ Y^{0*} are observed in an experiment performed with the ANKE spectrometer at COSY-Julich at a beam momentum of 3.65 GeV/c. Two final states were investigated simu
Results from a partial-wave analysis of the reaction $gamma p rightarrow K^+ Lambda$ are presented. The reaction is dominated by the $S_{11}(1650)$ and $P_{13}(1720)$ resonances at low energies and by $P_{13}(1900)$ at higher energies. There are smal
We present calculations of the invariant mass spectra of the $Lambda$p system for the exclusive $p p to K^+ Lambda p$ reaction with the aim of studying the final state interaction between the $Lambda$-hyperon and the proton. The reaction is described
Low-energy data on the three charge states in $gamma p to K^+(Sigmapi)$ from CLAS at JLab, on $K^-pto pi^0pi^0Lambda$ and $pi^0pi^0Sigma$ from the Crystal Ball at BNL, bubble chamber data on $K^-ptopi^-pi^+pi^{pm}Sigma^{mp}$, low-energy total cross s
Employing the Bonn-Gatchina partial wave analysis framework (PWA), we have analyzed HADES data of the reaction $p(3.5GeV)+pto pK^{+}Lambda$. This reaction might contain information about the kaonic cluster $ppK^-$ via its decay into $pLambda$. Due to
