Resumen

Three-body hadronic models with separable pairwise interactions are formulated and solved to calculate resonance masses and widths of L=0 Nδ and δδ dibaryons using relativistic kinematics. For Nδ, I(JP)=1(2+) and 2(1+) resonances slightly below threshold are found by solving πNN Faddeev equations. For δδ, several resonances below threshold are found by solving πNδ Faddeev equations in which the Nδ interaction is dominated by the 1(2+) and 2(1+) resonating channels. The lowest δδ dibaryon resonances found are for I(JP)=0(3+) and 3(0+), the former agreeing well both in mass and in width with the relatively narrow D03(2370) resonance observed recently by the WASA@COSY Collaboration. Its spin-isospin symmetric partner D30 is predicted with mass around 2.4 GeV and width about 80 MeV.
