Wilson line
In gauge theory, a Wilson loop (named after Kenneth G. Wilson) is a gauge-invariant observable obtained from the holonomy of the gauge connection around a given loop. In the classical theory, the collection of all Wilson loops contains sufficient information to reconstruct the gauge connection, up to gauge transformation.
In quantum field theory, the definition of Wilson loop observables as bona fide operators on Fock space (actually, Haag's theorem states that Fock space does not exist for interacting QFTs) is a mathematically delicate problem and requires regularization, usually by equipping each loop with a framing. The action of Wilson loop operators has the interpretation of creating an elementary excitation of the quantum field which is localized on the loop. In this way, Faraday's "flux tubes" become elementary excitations of the quantum electromagnetic field.
Wilson loops were introduced in the 1970s in an attempt at a nonperturbative formulation of quantum chromodynamics (QCD), or at least as a convenient collection of variables for dealing with the strongly-interacting regime of QCD. The problem of confinement, which Wilson loops were designed to solve, remains unsolved to this day.
The fact that strongly-coupled quantum gauge field theories have elementary nonperturbative excitations which are loops motivated Alexander Polyakov to formulate the first string theories, which described the propagation of an elementary quantum loop in spacetime.
Wilson loops played an important role in the formulation of loop quantum gravity, but there they are superseded by spin networks, a certain generalization of Wilson loops.
In particle physics and string theory, Wilson loops are often called Wilson lines, especially Wilson loops around non-contractible loops of a compact manifold.

Monday in Hawkville: Russell Wilson picks up far beyond where he left off A recap of the activities at Virginia Mason Athletic Center for May 20, as the Seahawks kicked off the OTA portion of their offseason program: FOCUS ON Russell Wilson. The Seahawks’ second-year quarterback made it difficult to not watch him, and coach Pete Carroll summed up the situation when asked how much farther along Wilson is this year compared to last year – when he had just been selected in the third round of the NFL Draft and still was competing for the starting job with the since-departed duo of Matt Flynn and Tarvaris Jackson.
