%X The results of a recent experiment measuring the reaction pp -> dK(+)K(0) near threshold are interpreted in terms of a spectator model that encapsulates the main features of the observed (K+K0) invariant mass distribution. A X 2 fit to this data leads to an imaginary part of the isovector scattering length in the KK channel of Im(a(1)) = -(0.63 +/- 0.24) fm. We then use the Flatte representation of the scattering amplitude to infer a value Re(a I) = - (0.02 +/- 0.02) fm for the real part under the assumption that scaling [V Baru, J. Haidenbauer, C. Hanhart, A. Kudryavtsev, U.G. Meissner, Eur. Phys. J. A 23 (2005) 523] is approximately satisfied. We show further that it is not possible to exclude the effects of pi(+)eta to (K+K0) channel coupling within the context of our model. (c) 2005 Elsevier B.V. All rights reserved.
