摘要

We report on the results of the search for the e + e − → K ± K S π ∓ process. Data with an integrated luminosity of 1.36 pb −1 collected in experiment with a spherical neutral detector (SND) on the VEPP-2M e + e − collider in the energy range from 1.36 to 1.38 GeV have been analyzed. The upper limits of the σ < 150 pb cross sections of the sought process have been established for an energy of 1.37 GeV at a confidence level of 90%.
