Dibaryons are subatomic particles composed of two baryons. Their formation, which occurs through interactions between baryons, is fundamental in big-bang nucleosynthesis, nuclear reactions including those happening within stars, and bridges the gap between nuclear physics, cosmology, and astrophysics. Fascinatingly, the strong force, responsible for the formation and the majority of the mass of nuclei, facilitates the formation of a plethora of different dibaryons with diverse quark combinations.
Nevertheless, these dibaryons are not commonly observed — the deuteron is currently the only known stable dibaryon.
To resolve this apparent dichotomy, it is essential to investigate dibaryons and baryon-baryon interactions at the fundamental level of strong interactions. In a recent publication in Physical Review Letters.
