Abstract

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 Faddeev calculations of L=0 nonstrange pion-assisted NΔ and ΔΔ dibaryon candidates. 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$\mathcal {D}_{30}$, the I(JP)=3(0+) exotic partner of D03(2370). Extensions to strangeness S=−1 dibaryons are briefly discussed.
