Abstract

Cross sections are presented for the inclusive photoproduction of KS0, , ,-, -, 0, and *(1385) at 20 GeV. An upper limit to - production is also given. The data come from 284 000 hadronic events photoproduced in the SLAC 1-m hydrogen-bubble-chamber hybrid facility exposed to a nearly monochromatic, polarized 20-GeV backscattered photon beam. A comparison of the KS0, , , and - rates per inelastic event to p data show that p rates are consistent with being higher than the p rates, providing evidence of an ss component of the photon. The pair cross sections for KS0KS0, KS0, KSo, and are presented. The xF distributions of the , , and - are compared to a quark-diquark fusion model, giving information on strange-baryon photoproduction mechanisms.
