abstract

  • The search for missing nucleon resonances using coupled channel analysis has mostly been concentrated on Nπ and KY channels, while the contributions of K*Y and KY* channels have not been investigated thoroughly mostly due to the lack of data. With an integrated luminosity of about 75 pb -1, the photoproduction data using a proton target recently collected by the CLAS Collaboration at Jefferson Lab with a photon energy range of 1.5-3.8 GeV provided large statistics for the study of light hyperon photoproduction through exclusive reactions. The reaction γp → K +π has been investigated. Preliminary results of the K*+ and K+Σ(1385) cross sections are not negligible compared with the KY channels. The π invariant mass spectrum is dominated by the Σ(1385) signal and no significant structure was found around the Σ (1480) region. Copyright © 2006 by World Scientific Publishing Co. Pvt. Ltd.
