Abstract: 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- system is rather constant for different invariant masses, there is an enhancement in the pK(-) system towards lower masses which could at least be partially connected to the influence of the Lambda (1405) resonance.
