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.
Measurements of the double differential cross sections for ππ and pπ production in pp collisions at the CERN ISR are presented for 5 c.m. energies s = 22, 30, 44, 53, 62 GeV . Charge and transverse momentum correlations are also reported.
We report on measurements of inclusive π 0 production at c.m. energies of 53 and 63 GeV, θ ≅90°, from p-p collisions at the CERN ISR. In the range 0.2< x t <0.45 the data can be described by a form: Ed 3 σ d p 3 ∝p − (6.6±0.8) t (1−x t ) (9.6±1.0) .
