Title: Strangeness Physics with CLAS at Jefferson Lab

Abstract

We review recent developments in strangeness photo- and electro- production off the proton and neutron, as investigated using CLAS in Hall B at Jefferson Lab. By measuring sufficient spin observables one can decompose the reaction mechanism into elementary amplitudes. We discuss progress toward this end in recent data from CLAS, including cross sections and spin observables. We next discuss new results on the mass distribution of the Lambda(1405), which shows signs of being a composite meson-baryon object of mixed isospin. The work on other hyperons such as the Xi resonances will be mentioned, and future prospects for the CLAS program outlined.
