Description

The spectrum of effective masses mpp of two protons produced in the p4He → nppd process is analysed. It is shown that the maximum at mpp ∼ 2.02 GeV/c2 can appear in this spectrum due to the one pion exchange mechanism if to suppose that the amplitude of the virtual π-meson absorption on deuteron has the singularity near the threshold of πd → NN reaction. The mechanism of the second maximum formation at mpp ∼ 2.14 GeV/c2 in the mpp-spectrum and the connection of the considered resonance maxima with the possible dibaryon resonance states are discussed
