abstract = {The pp -> ppK+K- reaction was measured below the phi
threshold at a beam energy of 2.568 GeV using the COSY-ANKE
magnetic spectrometer. By assuming that the four-body phase
space is distorted only by the product of two-body final
state interactions, fits to a variety of one-dimensional
distributions permit the evaluation of differential and
total cross sections. The shapes of the distributions in the
Kp and Kpp invariant masses are reproduced only if the K-p
interaction is even stronger than that found at higher
energy. The cusp effect in the K+K- distribution at the
K0K0bar threshold is much more clear and some evidence is
also found for coupling between the K-p and K0bar n
channels. However, the energy dependence of the total cross
section cannot be reproduced by considering only a simple
product of such pair-wise final state interactions.},
