【 摘 要 】

Experimental evidence for I(JP)=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(JP)=3(0+) exotic partner of D03(2370).
