The e+ e- --> K(s)0K +/- pi -/+ and K+ K- pi-0 cross sections have been measured in the energy interval 1350 less-than-or-equal-to square-root s less-than-or-equal-to 2400 MeV with the DM2 detector at DCI. The K(s)0 K +/- pi -/+ cross section shows the contribution of an isoscalar vector meson at almost-equal-to 1650 MeV/c2 in agreement with a previous experiment. The low statistics K+ K- pi-0 measurement is consistent with the above result.

Abstract
The e+ e- --> K(s)0K +/- pi -/+ and K+ K- pi-0 cross sections have been measured in the energy interval 1350 less-than-or-equal-to square-root s less-than-or-equal-to 2400 MeV with the DM2 detector at DCI. The K(s)0 K +/- pi -/+ cross section shows the contribution of an isoscalar vector meson at almost-equal-to 1650 MeV/c2 in agreement with a previous experiment. The low statistics K+ K- pi-0 measurement is consistent with the above result.File in questo prodotto:
