K+Λ and K+Σ0 Photoproduction in View of the New CLAS Data

Abstract

Abstract We have investigated the effect of the new CLAS data consisting of the recoiled Λ polarization P, photon asymmetry Σ, target asymmetry T, and the double polarizations Ox and Oz , on the latest isobar models constructed for the kaon photoproduction processes γp → K +Λ and γp → K +Σ0. We found that those data might have significant effect, especially in the K +Λ channel, where apparent changes are observed in the predicted differential cross sections after including the new CLAS data in the fitting database. The isobar model for the K +Λ photoproduction must be accordingly modified in order to improve the agreement between model calculation and previous experimental data.
