Determination of the Polarization Observables , , and for the Reaction

Many excited nucleon states (s) predicted by quark models, but not observed in channels, are expected to couple strongly to kaon-hyperon (KY) channels. While in the last decade data have been published for KY photoproduction off the proton, data off the neutron are scarce. In this paper we present preliminary results for the polarization observables P, , and for the reaction , where (p) denotes the spectator proton. The observables cover photon energies, , between 0.9 and 2.6 GeV and kaon center-of-mass angles, , between and 1. The data were collected in experiment E06-103 (g13) with the CLAS detector at the Thomas Jefferson National Accelerator Facility using a circularly-polarized photon beam and an unpolarized liquid deuterium target. We also discuss the effect of neutron binding on the observables. Our study is part of a broader effort by the g13 group to provide cross sections and polarization observables for meson photoproduction off the neutron and is expected to have a significant impact on the research.
