Findings

Evidence of s-channel structures suggestive of high-mass baryon resonances.

High-precision cross section and polarization measurements with polarized beams.

Insights into baryon resonance coupling to kaons and hyperons.

Abstract

An extensive program of strange particle production off the nucleon is currently underway with the CEBAF Large Acceptance Spectrometer (CLAS) in Hall B at Jefferson Laboratory. This talk will emphasize strangeness electroproduction in the baryon resonance region between W=1.6 and 2.4 GeV, where indications of s-channel structure are suggestive of high-mass baryon resonances coupling to kaons and hyperons in the final state. Precision measurements of cross sections and polarization observables are being carried out with highly polarized electron and real photon beams at energies up to 6 GeV. The near-term and longer-term future of this program will also be discussed.
