Strangeness Photoproduction with the Saphir Detector
D. Menze
Abstract
Statistically improved data of total cross sections and of angular distributions for differential cross sections and hyperon recoil polarizations of the reactions γp --> K+ Λand γp --> K+ Σ0 have been collected with the SAPHIR detector at photon energies between threshold and 2.0 GeV. Here total cross section data up to 1.5 GeV are presented. The opposite sign of Λand Σpolarization and the change of sign between forward and backward direction could be confirmed by higher statistics. A steep threshold behaviour of the K+ Λtotal cross section is observed.
