Abstract
Preliminary results of examining the system of two K-S mesons in the region of comparatively high transferred momenta are reported. The events were ob served in the pi (-)p interactions at an energy of 40 GeV on the ITEP 6-m m agnetic spectrometer with a neutral trigger. At transferred momenta \t\ > 0 .5 GeV2, a maximum with width Gamma similar or equal to 10 MeV was observed in the KSKS system at a mass of 1545 MeV with statistical significance of no less than 6 standard deviations. This phenomenon can be interpreted as t he manifestation of a resonance with the indicated parameters. (C) 2000 MAI K "Nauka/Interperiodica".
