N2 - We discuss a new type of L = 0 positive-parity dibaryons, πBB′, where the dominant binding mechanism is provided by resonating p-wave pion-baryon interactions. Recent calculations of such pion assisted dibaryons are reviewed with special emphasis placed on the non-strange I(JP) = 1(2+) NΔ dibaryon π12(2150) studied recently at JLab, and on the 0(3+) ΔΔ dibaryon D03(2380) discovered recently by the WASA-at-COSY Collaboration. We discuss recent searches by the HADES Collaboration at GSI and by the E15 and E27 Experiments at J-PARC for a strangeness S = - 1 I(JP) = 12(0-) K-pp dibaryon and perhaps also for a strange I(JP) = 3/2(2+) NΣ(1385) pion assisted dibaryon Γ3/22(2270). Charm C = +1 dibaryons, predicted with the same I(JP) values, are also briefly reviewed.
