We investigate, by means of numerical lattice simulations, the θ-dependence of the critical deconfinement temperature of SU(N) gauge theories at large N : Tc(θ) = Tc(0)[1 – Rθ2 + O(θ4)], with R ~ O(1/N2). We follow two different strategies to determine R, one based on the calculation of the latent heat of the transition and on the jump of the topological susceptibility at the θ = 0 critical point, the other relying on a direct probe of Tc(θ) by means of imaginary-θ Monte Carlo simulations.

Abstract
We investigate, by means of numerical lattice simulations, the θ-dependence of the critical deconfinement temperature of SU(N) gauge theories at large N : Tc(θ) = Tc(0)[1 – Rθ2 + O(θ4)], with R ~ O(1/N2). We follow two different strategies to determine R, one based on the calculation of the latent heat of the transition and on the jump of the topological susceptibility at the θ = 0 critical point, the other relying on a direct probe of Tc(θ) by means of imaginary-θ Monte Carlo simulations. Our results show that R follows the expected large-N scaling.File in questo prodotto:
