Color confinement and dual superconductivity of the vacuum. IV
M. D'Elia, A. Di Giacomo, B. Lucini +2
A scaling analysis is made of the order parameter describing monopole condensation at the deconfining transition of N_f=2 QCD around the chiral point. In accordance with scaling pr…
Chiral transition and deconfinement in N_f = 2 QCD
M. D'Elia, A. Di Giacomo, B. Lucini +2
The transition is studied by means of a disorder parameter detecting condensation of magnetic monopoles in the vacuum. The deconfining transition is found to coincide with the chir…
Deconfining transition in two-flavor QCD
J. M. Carmona, M. D'Elia, L. Del Debbio +4
The order and the nature of the finite-temperature phase transition of QCD with two flavors of dynamical quarks is investigated. An analysis of the critical exponent of the specifi…
The abelian projection revisited
A. Di Giacomo, G. Paffuti
Abelian projection is reanalysed in the frame of the SU(N) Higgs model. The extension to QCD is discussed. It is shown that dual superconductivity of the vacuum is an intrinsic pro…
Abelian projection in SU(N) gauge theories
L. Del Debbio, A. Di Giacomo, B. Lucini +1
The abelian projection in SU(N) gauge theories is discussed in detail, as well as the construction of a disorder parameter to study dual superconductivity as a mechanism for color…
Confinement and monopole condensation: some properties of the disorder parameter
A. Di Giacomo, G. Paffuti
We demonstrate that the disorder parameter to detect dual superconductivity in the confining phase of QCD is the v.e.v. of a magnetically charged, Dirac like, gauge invariant…
