Dibaryons are subatomic particles composed of two baryons, or elementary particles made of three quarks. Synonyms for the word dibaryon include double baryon, diquark, baryonic molecule, and baryon-baryon system. Double baryon is a simple way to describe the structure of dibaryons, while diquark emphasizes the two-quark composition of the particle. Baryonic molecule underscores the idea of two interacting baryons, similar to the way atoms combine to form molecules. Baryon-baryon system is a scientific term that is often used to describe the relative positions and interactions of dibaryons in high-energy physics experiments.
