Measurement of the reaction gamma proton –> K0 Sigma+ for photon energies up to 2.65 GeV with SAPHIR at ELSA — •Ralf Lawall — Nussallee 12, 53115 Bonn

Results are presented for cross sections as a function of the photon energy and the production angle in the CMS and for the polarization of the Sigma+ in the energy range from the production threshold up to 2.65 GeV. The data are compared with other measurements and with predictions of theoretical models.
