Experimental results for the cross-sections, the effectivemass distributions, the angular distributions and correlations are presented for the reaction$\bar p$p → 3π−3π+. All the multipion mass distributions and the ππ angular correlations are described in terms of a final-state interaction model including theδ00 andδ11 ππ phase shifts, as well as an A2 effect.

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.
