SU(N) gauge theories in the presence of a topological term

Debbio, L. D.; Panagopoulos, Haralambos G.; Vicari, E. (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

Bonati, C.; D'Elia, M.; Panagopoulos, Haralambos G.; Vicari, E. (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 ...
