Recent Kaon Photoproduction Results from CLAS — •David Ireland — University of Glasgow, Glasgow, United Kingdom
Kaon photoproduction in the resonance region affords an ideal opportunity to study the spectrum of nucleon resonances. It is, however, crucial that polarization observables be measured in order to disentangle contributing processes. The prospect of a “complete” measurement being made is not far off, but a number of double polarization observables have already been measured using the CLAS detector at the Thomas Jefferson National Accelerator Facility in the US. This talk will review some of the recent results for the γ p→ K+Λ and γ p→ K+Σ0 reactions. Preliminary measurements of the photon beam asymmetry, Σ, and the double polarization observables Ox and Oz, using a beam of linearly polarized tagged photons will also be discussed.
