“…In that time, the first experimental indications appeared for existence of the number of dibaryon states. In particular, in elastic scattering of polarized protons p + p, the signals of a whole series of isovector dibaryons in 1 D 2 , 3 F 3 , 1 G 4 , etc., partial waves were found [8,9,10] (see also later experimental works [11,12,13]). Besides that, rather convincing though indirect indications for an isoscalar dibaryon with quantum numbers I(J P ) = 0(3 + ) were found in measurements of the outgoing proton polarisation in the deuteron photodisintegration process γd → pn at energies E γ ≃ 400-600 MeV [14,15,16].…”

“…However, a number of more sensitive polarization characteristics were not reproduced within the framework of conventional meson-exchange models [32,33]. So, it was claimed [24] that excitation of the intermediate dibaryon resonances found in elastic pp scattering [5,9,10] should be taken into account in the NN → dπ process as well.…”

Processes of one-and two-pion production in NN collisions are considered in connection with excitation of intermediate dibaryon resonances. In particular, relative contributions of the conventional meson-exchange and dibaryon excitation mechanisms in the reaction pp → dπ + are investigated in detail. Inclusion of the intermediate isovector dibaryon resonances is shown to essentially improve the description of experimental data for this reaction, provided the soft meson-baryon form factors consistent with πN elastic scattering are used. Manifestation of the intermediate isoscalar and isovector dibaryons in the two-pion production processes is also studied. The role of the isovector dibaryon resonances in the reaction pp → ppππ is discussed for the first time. An explanation of the observed strong differences between two-pion production cross sections in pn and pp collisions based in part on the analysis of dibaryon structure is suggested.

After a historical review, I present the progress in the field of realistic NN potentials that we have seen in recent years. A new generation of very quantitative (high-quality/high-precision) NN potentials has emerged. These potentials will serve as reliable input for microscopic nuclear structure calculations and will allow for a systematic investigation of off-shell effects. The issue of three-nucleon forces is also discussed.
