Baryon vs Diquark - What's the difference?
baryon | diquark |
(particle) A heavy subatomic particle created by the binding of quarks by gluons; a hadron containing three quarks. Baryons have half-odd integral spin and are thus fermions. This category includes the common proton and neutron of the atomic nucleus.
(physics) 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.
