Baryon resonances and polarization transfer in hyperon photoproduction

Abstract

A partial wave analysis is presented of data on photoproduction of hyperons including single and double polarization observables. The large spin transfer probability reported by the CLAS collaboration can be successfully described with an isobar partial wave analysis.
