Diquark

Encyclopedia : D : DI : DIQ : Diquark

---

In quark-diquark models, a diquark, or diquark correlation/clustering, is an hypothetical state of two quarks grouped inside a baryon (that consists of three quarks)^[1]. The diquark is often treated as a single particle with which the third quark interacts via the strong interaction. The existence of diquarks inside the nucleons is a disputed issue, but it helps to understand some nucleon properties and to reproduce experimental data sensitive to the nucleon structure.
