Confinement

Why is it interesting?

Quarks and gluons have never been observed freely in nature. Hence, there must be a reason, why they only appear in combination with other particles. The corresponding mechanism is called confinement.

Layman

Explanations in this section should contain no formulas, but instead colloquial things like you would hear them during a coffee break or at a cocktail party.

Student

Renormalizationgroup arguments yield a large effective coupling for large quark separation. ' This suggests that perturbation theory may break down at large distances, which would explain the lack of perturbative evidence for confinement. Eliminating ultraviolet divergences with the artifice of a lattice, Wilson has investigated the strong-coupling limit of gauge theories. ' In this limit the theory becomes one of quarks connected by strings, and confinement is natural.
