Search for hyperon resonances with spark chambers

The Princeton-Pennsylvania accelerator 15-in. hydrogen bubble chamber was used to investigate r+p associated production a t 1.7 GeV/c. Approximately 4000 events were found; about half of these were in the Z+Kf channel. The AKf?r+ channel dominates the remaining half of the data. We find evidence for the existence of a T = 1 hyperon resonance a t 1475f 15 MeV with a width of 3 0 f 15 MeV in the AK+r+, Z+K+7r0, Z°K+?r+, and ~~+ z " c h a n n e l s .The cross sections of the strange-particle channels and the branching ratios of various resonances are also presented.
