On dibaryon production in D + D → X + D reaction

Analysis of experimental data taken at JINR synchrophasotron has revealed that quasi-resonant peaks (dibaryons) observed in the two-proton effective mass distribution from reactions np → ppπ− mπ0 and np → ppπ+π−π− mπ0, m = 0, 1 were also detected in D + D → X + D reaction by other experimental group. Besides, the data on D + D → X + D hint at a possibility of existence of dibaryons with I = 0 and masses in the vicinity of 2.4 and 2.5 GeV, which were predicted in the frame of the MIT 6-q bag model.
