Diquark

[clarification needed] When both quarks are correlated in this way they tend to form a very low energy configuration.

Even though they may contain two quarks they are not color neutral, and therefore cannot exist as isolated bound states.

So instead they tend to float freely inside hadrons as composite entities; while free-floating they have a size of about 1 fm.

Diquarks are the conceptual building blocks, and as such give scientists an ordering principle for the most important states in the hadronic spectrum.

[clarification needed] An experiment was conducted using diquarks in an attempt to study the Λ and Σ baryons that are produced in the creation of hadrons created by fast-moving quarks.
