Abstract

An analysis of the K0K0system at threshold produced in the final states pp→K0sK0s(nπ ) at 700-760 MeV/c, is presented. A simultaneous fit to the pp phase shifts and inelasticities and to the KS0KS0 effective-mass distributions using parametrizations which take into account the analytical and unitarity properties of the I = 0 S-wave amplitudes is performed. The behaviour of the eigenphases and the unphysical Riemann sheet structure for different solutions is studied.
