Popis: We study ππ correlations in the exclusive reactions p p → 2π + 2π − and p p → 2π + 2π − π 0 at rest with complete reconstruction of the kinematics for each event. A new analysis technique has been developed which is model independent. With this new technique, which relies on double-differential distributions, no reference sample is needed to extract the correlation signal. The correlations are studied as a function of the four-pion invariant mass.
