Abstract

The order parameter of the Schwinger model is calculated in the euclidean functional integral approach. It is shown that the symmetry breaking angle θ is intimately connected with the boundary condition imposed on the fermions. The transition to the euclidean description involves both imaginary time and imaginary θ.
