Analysis demonstrates the formation of dibaryonic systems in nucleon-nucleon collisions, suggesting new insights into the Roper resonance.
In many reactions leading to excitations of the nucleon, the Roper resonance \(N^*(1440)\) can be sensed only very indirectly by complex partial-wave analyses. In nucleon–nucleon collisions the isoscalar single-pion production as well as specific two-pion production channels present the Roper excitation free of competing resonance processes at a mass of 1370 MeV and a width of 150 MeV. A detailed analysis points to the formation of \(N^*(1440)N\) dibaryonic systems during the nucleon–nucleon collision process similar to what is known from the \({ Δ }(1232)N\) threshold.
