Experimental results on antiproton-proton annihilations at 5 incident momenta in the range 1.22–1.35 GeV/ c into final states with at least one visible K 1 0 meson are presented. Based on a total of 5855 events, cross sections and resonance fractions for all experimentally accessible final states are determined. The total cross section for annihilation into strange particles with at least one visible K 1 0 is 2069 ± 45 ub. Copious resonance production is observed but there is no significant evidence for the formation of a resonance in the s -channel.

Study of a $K^0_S K^0_S$ Plus Threshold Enhancement Observed in the Final States $\bar{p} p \to K^0_S K^0_S$ Pions at 700-{MeV}/$c$ to 760-{MeV}/$c$

An analysis of the K 0 K 0 system at threshold produced in the final states p p → K S 0 K S 0 ( n π) at 700–760 MeV/ c , is presented. A simultaneous fit to the ππ phase shifts and inelasticities and to the K S 0 K S 0 effective-mass distributions using parametrizations which take into account the analytical and unitarity properties of the I = 0 S-wave amplitudes is performed. The behaviour of the eigenphases and the unphysical Riemann sheet structure for different solutions is studied.
