Two-dimensional QCD in the Wu-Mandelstam-Leibbrandt prescription
Two-dimensional QCD in the Wu-Mandelstam-Leibbrandt prescription
We find the exact nonperturbative expression for a simple Wilson loop of arbitrary shape for $\mathrm{U}(N)$ and $\mathrm{SU}(N)$ Euclidean or Minkowskian two-dimensional Yang-Mills $({\mathrm{YM}}_{2})$ theory regulated by the Wu-Mandelstam-Leibbrandt gauge prescription. The result differs from the standard pure exponential area law of ${\mathrm{YM}}_{2}$ theory, but still exhibits confinement as well …
