Dibaryons: quarks in six-pack

Mikhail Bashkanov, School of Physics and Astronomy, University of Edinburgh.

For a long time, physicists were only able to reliably verify two different classes of hadrons: volatile mesons comprising one quark and one antiquark and baryons consisting of three quarks. However, the last decade became a tipping point in such a vision. Observation of meson-meson molecules, especially after the discovery of XYZ-states in the charm sector, of meson-baryon states, in particular dynamically generated resonances and charm pentaquarks, and finally the discovery of the existence of dibaryons demonstrate that the naïve quark picture is outdated and that nature is much richer and more complex. So searches for exotic phenomena in strong interaction scenarios has now become a world-wide trend.
The talk will be devoted to a recent discovery of the first non-trivial dibaryon resonance - "inevitable dibaryon", d*(2380). Various aspects, including decay properties, internal structure and possible implication on the other fields will be discussed. Small mass (M_d*=2380MeV), narrow width (Gamma_d*=80MeV) and large "hidden color" component make d*(2380) to be a perfect tool to study the interplay between quark and molecular-type degrees of freedom in QCD.
Few other ongoing dibaryon programs will be outlined in the end.
