The Σ+ hyperon production was measured at the COSY-11 spectrometer via the pp→nK+Σ+ reaction at excess energies of Q=13 MeV and Q=60 MeV. These measurements continue systematic hyperon production studies via the pp→pK+Λ/Σ0 reactions where a strong decrease of the cross section ratio close-to-threshold was observed. In order to verify models developed for the description of the Λ and Σ0 production...
The total cross section of the reaction pp→ppK+K− has been measured at excess energies Q=10 MeV and 28 MeV with the magnetic spectrometer COSY-11. The new data show a significant enhancement of the total cross section compared to pure phase space expectations or calculations within a one boson exchange model. In addition, we present invariant mass spectra of two particle subsystems. While the K+K−...
