Abstract

The ANKE@COSY data on the reaction of two-pion production in the GeV region are analyzed within the theoretical model by Platonova and Kukulin. The model includes excitation of the dibaryon resonance D_IJ = D₀₃(2380) with the spin J = 3 and isospin I = 0 observed by the WASA@COSY in the reaction pn → dπ⁰π⁰, and its decay D₀₃ → D₁₂ + π → d + π + π, where D₁₂(2150) is another dibaryon resonance. Distributions on the invariant masses of the final dππ and ππ systems are calculated.
