The cross sections for K+p interactions at a center-of-mass energy of 3 GeV (4.3 GeV/c incident momentum) have been determined for the K+pπ+π−, K0pπ+π0, and K0π+π+n final states. The shape of the differential cross section dσdt′ for the quasi-two-body final state K*0(890)+Δ++(1236) is not a single exponential. Characteristics of the low-mass Kππ and pππ enhancements are discussed.

Study of $\pi \pi$ Scattering Amplitudes in the Reaction $\pi^+ p \to \Delta^{++} \pi^0 \pi^0$ at 8.0-{GeV}

An experiment studying the reaction π+p→Δ++π0π0 using the Argonne National Laboratory 1.5-m streamer chamber combined with a lead-glass hodoscope is described. The data were analyzed in terms of π+π−→π0π0 scattering, and the details of the extrapolation to the pole are discussed. An energy-independent amplitude analysis from threshold to 2.3 GeV is presented. In this analysis the f0(1270), the h0(2040), and a JP=2+ state at 1.8 GeV with a width of 0.280 GeV are observed. The amplitude ambiguity arising from analyses of π+π−→π+π− data in the 1.6-GeV region is resolved. An energy-dependent phase-shift analysis from 1.0 to 1.5 GeV is presented.
