摘要：

Many baryon resonances are predicted studying the channels with pi, but very few established. This is the so-called "missing resonance" problem. It is important to provide data to investigate the spectrum of baryon (N* and Delta) resonances, with the decay in KY. A comprehensive study of the electromagnetic strangeness production has been undertaken at Jefferson Lab using circularly and linearly polarized photon beam and polarized hydrogen and deuterium target. Recent results in strangeness photoproduction on protons, including cross sections and spin observables, are discussed in this paper, as well preliminary results on photoproduction on bound neutron. Also an overview of the future perspectives for the 12 GeV upgrade.
