We study the phase diagram of non-Abelian pure gauge theories in the presence of a topological θ term. The dependence of the deconfinement temperature on θ is determined on the lattice both by analytic continuation and by reweighting, obtaining consistent results.

Abstract
We study the phase diagram of non-Abelian pure gauge theories in the presence of a topological θ term. The dependence of the deconfinement temperature on θ is determined on the lattice both by analytic continuation and by reweighting, obtaining consistent results. The general structure of the diagram is discussed on the basis of large-N considerations and of the possible analogies and dualities existing with the phase diagram of QCD in the presence of an imaginary baryon chemical potential.File in questo prodotto:
