The effects of resonance production on correlations in final states containing kaons in p p annihilations at 0.76 GeV c have been in detail. We show that correlation distributions of unlike kaon pairs, K S 0 K ± , can be completerly by resonance production. However, for like kaon pairs, K S ) K S 0 , we require the added effects of second-order interference. Using this interference effect we are able to measure the dimensions of the emission region for kaons in p p annihilations at low energy as R = 0.9 ± 0.2 fm.

A study of the inclusive production of π − , η , ϱ 0 , ω ad f mesons in p p annihilation at 0.7 GeV/ c is presented. Topological and channel cross sections are determined. Longitudinal and transversal momentum distributions of non-strange mesons are studied. It is deduced that nearly 48% of all negative pions arise from the decay of η , ϱ 0 , ω and f mesons.
