The θ-dependence of the SU(N) critical temperature at large N
We investigate, by means of numerical lattice simulations, the θ-dependence of the critical deconfinement temperature of SU(N) gauge theories at large N : T<inf>c</inf>(θ) = T<inf>c</inf>(0)[1 – Rθ2 + O(θ4)], with R ~ O(1/N2). We follow two different strategies to determine R...

| Sumario: | We investigate, by means of numerical lattice simulations, the θ-dependence of the critical deconfinement temperature of SU(N) gauge theories at large N : T<inf>c</inf>(θ) = T<inf>c</inf>(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 T<inf>c</inf>(θ) by means of imaginary-θ Monte Carlo simulations. Our results show that R follows the expected large-N scaling. © The Author(s) 2024. |
