title = "Weak coupling perturbative calculations of the Wilson loop in lattice gauge theory",
abstract = "Weak coupling perturbative calculations of the Wilson loop in lattice gauge theory are carried out numerically up to order g4. Comparison of the results with those of the Monte Carlo calculations shows that there exists a non-perturbative contribution of an essential singularity type which may be identified as the string tension.",
