Description
Inspired by a recent observation of a narrow resonance-like structure around 2360 MeV in the pn → dπ0π0 cross section, we investigate the possibility of forming NN*(1440) quasi-bound state by meson exchange potential. With parameters of the t-channel π, σ, ρ and ω exchanges determined by relevant NN scattering and N*(1440) decay processes, it is found that a NN*(1440) quasi-bound state with the same quantum numbers as the deuteron can be formed with binding energy about 20 MeV.
