Abstract

Using the approach developed in [V. Azcoiti, G. Di Carlo, A. Galante, V. Laliena, \textit{Phys. Lett.} \textbf{B563}, (2003) 117], we are able to reconstruct the behavior of the massive 1-flavor Schwinger model with a θ\theta term and a quantized topological charge. We calculate the full dependence of the order parameter with θ\theta. Our results at θ=π\theta = \pi are compatible with Coleman's conjecture on the phase diagram of this model.
