Free energy and theta dependence of SU(N) gauge theories
L. Del Debbio, H. Panagopoulos, E. Vicari
We study the dependence of the free energy on the CP violating angle theta, in four-dimensional SU(N) gauge theories with N >= 3, and in the large-N limit. Using the Wilson lattice…
Deconfining transition in Full QCD
J. M. Carmona, M. D'Elia, L. Del Debbio +4
We present evidence that in full QCD with two dynamical quarks confinement is produced by dual superconductivity of the vacuum as in the quenched theory. Preliminary information is…
Color confinement and dual superconductivity in unquenched QCD
J. M. Carmona, M. D'Elia, L. Del Debbio +4
We report on evidence from lattice simulations that confinement is produced by dual superconductivity of the vacuum in full QCD as in quenched QCD. Preliminary information is obtai…
Color confinement and dual superconductivity in full QCD
J. M. Carmona, M. D'Elia, L. Del Debbio +3
We report on evidence that confinement is related to dual superconductivity of the vacuum in full QCD, as in quenched QCD. The vacuum is a dual superconductor in the confining phas…
Center vortices and k-strings
Luigi Del Debbio, Dmitri Diakonov
The vortex contribution to the -string tensions is computed for SU() gauge theories. We deduce the surface densities needed to reproduce the sine scaling and the Casimir scal…
Theta dependence of SU(N) gauge theories
Luigi Del Debbio, Haralambos Panagopoulos, Ettore Vicari
We study the dependence of four-dimensional SU() gauge theories, for and in the large-N limit. We use numerical simulations of the Wilson lattice formulation of ga…
