Abstract
The results of an extensive campaign of measurements of the π→ππ process in the nucleon and nuclei at intermediate energies are presented. The measurements were motivated by the study of strong ππ correlations in nuclei. The analysis relies on the composite ratio View the MathML source, which accounts for the clear effect of the nuclear medium on the ππ system. The comparison of the View the MathML source distributions for the (ππ)I=J=0 and (ππ)I=0,J=2 systems to the model predictions indicates that the View the MathML source behavior in proximity of the 2mπ threshold is explainable through the partial restoration of chiral symmetry in nuclei.
