Mechanism of K − p → ηΛ Reaction Near Threshold

The pp → K + nΣ + reaction near threshold

Inclusive K+ production in proton-proton collisions has been measured at a beam energy of 2.16GeV using the COSY-ANKE magnetic spectrometer. The resulting spectrum, as well as those corresponding to K+p and K+π+ correlated pairs, can all be well described using consistent values of the total cross sections for the pp → K+pΛ, pp → K+pΣ0, and pp → K+nΣ+ reactions. While the resulting values for Λ...

Near - threshold η production in the p d → p d η reaction

The total cross section of the p d → p d η reaction has been measured at two energies near threshold by detecting the final proton and deuteron in a magneti spectrometer. The values are somewhat larger than expected on the basis of two simple theoretical estimates. PACS: 13.60.Le, 25.10.+s, 25.40.Ve

STUDY OF THE NEAR THRESHOLD pp→ ppK+K− REACTION IN VIEW OF THE K+K− FINAL STATE INTERACTION∗

Measurements of the pp→ ppK+K− reaction, performed near the kinematical threshold with the experiment COSY-11 at the Cooler Synchrotron COSY, reveal a significant discrepancy between obtained excitation function and theoretical expectations neglecting interactions of kaons. In order to deepen our knowledge about the low energy dynamics of the ppKK system we investigated population of events for...
