A study of the reactions K0p→Λπ+ (backward) and K0p→∑0π+ (backward) for kaon momenta between 1 and 8 GeV/c☆

Abstract We present results for the reactions K 0 p →Λπ + and K 0 p →∑ 0 π + , for |u'| GeV /c) 2 and kaon momenta between 1 and 8 GeV/ c . The experiment was performed ina 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 π N scattering.
