Photoproduction of Strange Particles

Abstract

The photoproduction of strange particles at photon energies between 1 and 6 BeV was studied using a 12-in. hydrogen bubble chamber. 283 events were observed in a sample of 865 000 pictures. Cross sections are presented. ${Y_1}^{*}\mathrm{}\left(1382\right)\mathrm{}$ and $K^{*} \mathrm{}\left(890\right)\mathrm{}$ production were observed in the $\gamma +p\to {\Lambda }^0+K+\pi$ reaction. There is evidence for ${\phi }^0$ production in the $\gamma +p\to p+K+\overline{K}$ reaction.
