N2 - The D03 dibaryon is generated dynamically as a resonance pole in a πNΔ′ three body model, where Δ ′ is a stable Δ baryon. Using separable interactions dominated by the Δ(1232) isobar for πN and by the D12(2150) isobar for NΔ′, with D12(2150) the NΔ dibaryon deduced in and constrained by D21 pp scattering, the model reduces to an effective two body problem for ΔΔ′ which is solved. The mass and width of D03 are found close to those of the I(JP)=0(3+) resonance peak observed by WASA-at-COSY in pion-production pn collisions at 2.37 GeV.
