Gauge fields like the photon field or gluon fields are usually described using gauge potentials. An alternative is to use Wilson lines. In contrast to gauge potentials, Wilson loops are completely gauge invariant. The set of all Wilson loops is sufficient to reconstruct the corresponding gauge potential. | Gauge fields like the photon field or gluon fields are usually described using gauge potentials.
