Sažetak
An analysis of new kaon electroproduction measurements at Jefferson Lab is presented for both proton and deuteron targets. Calculations based upon quantum hadrodynamics are compared to the experimental longitudinal and transverse separated cross sections for elementary KΛ production. Also confronted by data are model predictions for d(e,e’K+)YN inclusive measurements with YN = Λn, Σ0n and Σ−p. In general, both proton and deuteron target experiments are reasonably well described. Finally, glueball production, possible with the anticipated Jefferson Lab beam energy upgrade, is discussed in conjunction with results from a QCD Hamiltonian calculation for the low-lying gluonia spectrum.
