Abstract
A correlated jet model which takes into account dynamical two-particle correlations besides exact kinematical ones is compared with data of the reaction π +p → p3 π +2 π −. The approximation of the dynamical correlation by the contributions of the resonances ϱ 0, Δ ++ and Δ 0 is shown to yield a good description of single-, two- and three-particle distributions. Short-range effects of two-pion azimuthal angular correlations are explained mainly by the decay of ϱ 0 being produced with limited transverse momentum.
