Abstract: The near threshold total cross section and angular distributions of K+K- pair production via the reaction pp --> ppK(+)K(-) have been studied at an excess energy of Q = 17 MeV using the COSY-11 facility at the cooler synchrotron COSY. The obtained cross section as well as an upper limit at an excess energy of Q = 3 MeV represent the first measurements on the K+K- production in the region of small excess energies where production via the channel pp --> pp Phi --> ppK(+)K(-) is energetically forbidden. The possible influence of a resonant production via intermediate scalar states f(0)(980) and a(0)(980) is discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
