Abstract

We have measured (K^-,K⁺) reaction at 1.67 GeV/c K^- at the KEK proton synchrotron. A scintillating fiber active target was employed to view both secondary interactions and decays of particles produced in the (K^-,K⁺) reaction. This tracking capability for the vertex region provides us for studying the fate of Ξ^- hypernuclei, which is advantageous over the previous two experiments. We present a preliminary result on the production cross sections for Ξ¹² Be, and also on the branching fractions into the decay modes with charged particles and/or Λ hyperon(s).
