Change of θ dependence in 4D SU(N) gauge theories across the deconfinement transition
(2013)We study the dependence of 4D SU(N) gauge theories on the topological θ term at finite temperature T. We exploit the lattice formulation of the theory, presenting numerical results for the expansion of the free energy up ...

Simulating a CP-violating topological term in gauge theories
(2012)We present recent results on the θ-dependence of four-dimensional SU(N) gauge theories, where θ is the coefficient of the CP-violating topological term in the Lagrangian. In particular, we study the scaling behavior of ...

SU(N) gauge theories in the presence of a topological term
(2008)We review recent results on the θ dependence of the ground-state energy and spectrum of four-dimensional SU(N) gauge theories, where θ is the coefficient of the CP-violating topological term F F in the Lagrangian. In ...

θ Dependence of 4D SU(N) gauge theories at finite temperature
(Proceedings of Science (PoS), 2013)We report a study of the dependence of 4D SU(N) gauge theories on the topological θ term at finite temperature, and in particular in the large-N limit. We show that theθ dependence drastically changes across the deconfinement ...
