Topological susceptibility of SU ( N ) gauge theories at finite temperature

  title={Topological susceptibility of SU ( N ) gauge theories at finite temperature},
  author={Luigi Del Debbio},
We investigate the large-N behavior of the topological susceptibility χ in four-dimensional SU(N) gauge theories at finite temperature, and in particular across the finite-temperature transition at Tc. For this purpose, we consider the lattice formulation of the SU(N) gauge theories and perform Monte Carlo simulations for N = 4, 6. The results indicate that χ has a nonvanishing large-N limit for T < Tc, as at T = 0, and that the topological properties remain substantially unchanged in the low… CONTINUE READING
