Abstract:The energy dependence of the total cross section for the pp −→ pK + Λ reaction was measured in the threshold region covering the excess energy range up to 7 MeV.Existing model calculations describe the slope of the measured cross sections well, but are too low by a factor of two to three in rate.The data were used for a precise determination of the beam momentum of the COSY-synchrotron.

The production of η mesons has been measured in the proton-proton interaction close to the reaction threshold using the COSY-11 internal facility at the cooler synchrotron COSY. Total cross sections were determined for eight different excess energies (ǫ) in the range from ǫ = 0.5 MeV to ǫ = 5.4 MeV.The energy dependence of the total cross section is well described by the available phase-space volume weighted by FSI factors for the proton-proton and proton-η pairs.

“…Simultaneously to the reaction under investigation elastically scattered protons have been recorded on tape and analysed. The differential cross section in the angular range of cos Θ CM = 0.45 to 0.75 was extracted and normalized to the EDDA data [33], in order to determine the luminosity which In Fig. 3 a comparison of the pp → ppπ 0 , pp → ppη, and pp → ppη ′ total cross sections is presented.…”

The pp → ppη ′ (958) reaction has been measured at COSY using the internal beam and the COSY-11 facility. The total cross sections at the four different excess energies Q = 1.5 M eV, 1.7 M eV, 2.9 M eV, and 4.1 M eV have been evaluated to be σ = 2.5 ± 0.5 nb, 2.9 ± 1.1 nb, 12.7 ± 3.2 nb, and 25.2 ± 3.6 nb, respectively.In this region of excess energy the η ′ (958) cross sections are much lower compared to those of the π 0 and η production.
