A search for the. xi. (2230) resonance in the p p yields K sub s K sub s channel at LEAR (Low Energy Antiproton Ring)
Seventeen measurements of differential and total cross sections of the {bar p}p {yields} K{sub s}K{sub s} reaction in the antiproton momentum range of 1.30 GeV/c to 1.57 GeV/c are presented. Most of these measurements are centered around the mass of the {xi}(2230) resonance first seen in the K{sup +}K{sup {minus}} and K{sub s}K{sub s} channel of the radiative decay of the J/{Psi} by the MARK III collaboration at SLAC. The trajectories of the charged decay products of the K{sub s} particles are recorded by two stacks of drift chambers and a set of plastic streamer tube planes. The {bar p}p {yields} K{sub s}K{sub s} {yields} {pi}{sup +}{pi}{sup {minus}}{pi}{sup +}{pi}{sup {minus}} events are reconstructed by a computer program and undergo a full kinematic fitting. A branching ratio upper limit, BR({bar p}p {yields} {xi}){center dot}BR({xi} {yields} K{sub s}K{sub s}), on the presence of the resonance is calculated. The experiment was performed by the PS185 collaboration at the Low Energy Antiproton Ring (LEAR) at CERN.
