  • Description: The associated strangeness dissociation at threshold has been studied at the COSY-11 facility measuring the hyperon and the K (+) K- meson pair production. Measurements of the near-threshold Lambda and Sigma(o) production via the pp --> pK(+) Lambda/Sigma(0) reaction (S. Sewerinet al., Phys. Rev. Lett. 83, 682 (1999)) at COSY-11 have shown that the Lambda/Sigma(o) cross-section ratio exceeds the value at high excess energies (Q greater than or equal to 300 MeV (A. Baldiniet al., Total Cross-Sections for Reactions of High-Energy Particles, Landolt-Bornstein, New Series, Vol. I/12 (Springer, Berlin, 1988))) by an order of magnitude. For a better understanding additional data have been taken between 13 MeV and 60 MeV excess energy. The near-threshold production of the charged kaon-antikaon pair is related to the discussion about the nature of the scalar states in the 1 GeV/c(2) mass range, i.e. the f(0)(980) and a(0)(980) (O. Krehl, R. Rapp, J. Speth, Phys. Lett. B 390, 23 (1997)). The interpretation as a K (K) over bar molecule is strongly dependent on the K-(K) over bar interaction which can be studied via the production channel. A first total cross-section value on the reaction pp --> pp K+ K- at an excess energy of 17 MeV (C. Quentmeieret al., Phys. Lett. B 515, 276 (2001)), i.e. below the phi production threshold, was measured.
