Abstract
The JETSET experiment (PS202) at CERN - LEAR uses an internal gas-jet target surrounded by a compact general-purpose detector. The initial physics programme involves the spectroscopy of hadronic states, including glueballs, hybrids and multi-quark states, in the mass range up to 2.4 GeV. Emphasis is put on the reactions p̅p→φφ, ωφ) and ωω, and also on p̅p→K̅K, K̅K* and K̅*K*, using antiprotons up to 2 GeV/c momentum. This report gives the physics motivation and objectives of the experiment, and it describes the experimental technique chosen. A detailed account is given of data around and above 2 GeV invariant mass, which were obtained by previous experiments using hadronic reactions and heavy quarkonium decays. Future possiblities include threshold studies in multi-kaon final states, as well as high-statistics studies of exclusive hyperon — antihyperon production.
