Numerous experimental and theoretical arguments in favor of the intermediate dibaryon generation in NN and 3N interactions are presented. Using some speciﬁc mechanism for the scalar ﬁeld production when the 2ħω-excited multi-quark system deexcites to the ground state one formulates a concept for σ-dressed dibaryon as a carrier of intermediate-range attraction and a reason for short-range repulsion in NN-interaction. It is argued that the basic mechanisms responsible for large lowering of the Roper-resonance and the dressed dibaryon masses should be very similar. The modern experimental data of a few groups seem to conﬁrm strongly the dibaryon picture in NN and 3N-interactions. Some important common features of the dibaryon and pomeron in highenergy NN scattering are discussed.
