K-string tensions in SU(N) gauge theories
Debbio, L. D.; Panagopoulos, Haralambos G.; Rossi, P.; Vicari, E. (2002)In the context of four-dimensional SU(AO gauge theories, we study the spectrum of the confining strings. We compute, for the SU(6) gauge theory formulated on a lattice, the three independent string tensions σk related to ...

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 ...

Topological susceptibility of SU(N) gauge theories at finite temperature
Debbio, L. D.; Panagopoulos, Haralambos G.; Vicari, E. (2004)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, ...
