NΔ and ΔΔ dibaryons

Experimental evidence for I(J^P)=0(3⁺) ΔΔ dibaryon D₀₃(2370) has been presented recently by the WASA-at-COSY Collaboration. Here I review new hadronic-basis calculations of L 0 nonstrange NΔ and ΔΔ dibaryon candidates. In particular, D₀₃(2370) is generated dynamically in terms of long-range physics dominated by pions, nucleons and Δ's. These calculations are so far the only ones to reproduce the relatively small D₀₃(2370) width of 70-80 MeV. Predictions are also given for the location and width of D₃₀, the I(J^P)=3(0+) exotic partner of D₀₃(2370).
