Abstract
A new isoscalar state in the two-baryon system with mass 2380 MeV and width 80 MeV denoted now d*(2380) has been detected in the experiments at the Juelich Cooler Synchrotron (COSY). Existence or influence of states with higher isospin is a subject of the experiment for studing of the π+π− production in pp collisions. Calculations taking into account isotensor dibaryon resonance in the ΔN with I(Jp
) = 2(1+) provide a good description of the pp → ppπ+π−
total and differential cross sections.
