Abstract
We present the current status of our work on the extraction of cross sections and polarizations for photoproduction of hyperon resonances on a hydrogen target ({gamma}p{yields}K{sup +}Y{sup *}) using existing data from the CEBAF Large Acceptance Spectrometer (CLAS). The cross sections and polarizations will be used for a simultaneous theoretical analysis of hyperon ground state and hyperon resonance production. Thus far we have identified the hyperon resonances {sigma}{sup 0}(1385), {lambda}(1405), and {lambda}(1520) through missing mass and invariant mass cuts in various decay channels, such as {lambda}{pi}{sup 0}, {lambda}{pi}{sup +}{pi}{sup -}, {sigma}{sup 0}{pi}{sup 0}, {sigma}{sup +}{pi}{sup -}, {sigma}{sup -}{pi}{sup +}, pK{sup -} and nK{sup 0}. We have not yet seen the resonances {lambda}(1600), {sigma}(1660), {lambda}(1670), {sigma}(1670) and {lambda}(1690), although they need to be included for the analysis of the hyperon ground state production.
