Observation of an isoscalar vector meson at ≃1650 MeV/c2 in the $$e^ + e^ - \to K\bar K\pi $$ Equation>reaction

The\\(e^ + e^ - \\to K_s^0 K^ \\pm \\pi ^ \\mp \\) andK+K−π0 cross sections have been measured in the energy interval\\(1350 \\leqq \\sqrt s \\leqq 2400\\) with the DM2 detector at DCI. The\\(K_s^0 K^ \\pm \\pi ^ \\mp \\) cross section shows the contribution of an isoscalar vector meson at ≈1650 MeV/c2 in agreement with a previous experiment. The low statisticsK+K−π0 measurement is consistent with the above result.
