A study of the reactions anti K0p → Λπ+ (backward) and anti K0p → Σ0π+ (backward) for kaon momenta between 1 and 8 GeV/c

We present results for the reactions anti K0p → Λπ+ and anti K0p → Σ0π+, for vertical stroke u' vertical stroke < 0.05 (GeV/c)2 and kaon momenta between 1 and 8 GeV/c. The experiment was performed in a neutral beam at the PS with a two arm spark chamber spectrometer. The cross sections show strong dependence on beam energy and momentum transfer u'. Λ polarization is compatible with zero. We compare energy dependence of the backward cross sections with the baryon exchange model from πN scattering. (orig.)
