Kaon electromagnetic production in Hall B Original Research Article

An extensive program of associated strange particle production off the proton is currently underway with the CEBAF Large Acceptance Spectrometer (CLAS) in Hall B at Jefferson Laboratory. This contribution emphasizes strangeness photo- and electro-production in the nucleon resonance region between W=1.6 and 2.3 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 both electron and real photon beams, which are available with high polarization at energies up to 6 GeV.
