Strangeness production on the neutron

Abstract

The production of hyperons in neutron-proton collisions near threshold is surveyed. The comparison of COSY-ANKE experimental data on inclusive K + production in pd and pp collisions shows that Λ production is about as strong in the pn channel as in pp. This is in agreement with a theoretical prediction. Exclusive measurements, involving the detection of either K 0 or K + mesons, have been also carried out at COSY-TOF and COSY-ANKE, respectively. The current status of these two experiments is discussed.
