- diquark
-
The hypothetical state of two quarks grouped inside a baryon consisting of three.
Some of this attraction is due to the scalar diquark content of the nucleon current.

Diquark — In quark–diquark models, a diquark, or diquark correlation/clustering, is the hypothetical state of two quarks grouped inside a baryon (that consists of three quarks) (Lichtenberg 1982). The diquark is often treated as a single particle with… … Wikipedia
Charmed baryons — are a category of composite particles comprising all baryons made of at least one charm quark. Since their first observation in the 1970s, a large number of distinct charmed baryon states have been identified. Observed charmed baryons have masses … Wikipedia
