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…
Spectrum of k-string tensions in SU(N) gauge theories
L. Del Debbio, H. Panagopoulos, P. Rossi +1
We compute, for the four-dimensional SU(4) and SU(6) gauge theories formulated on a lattice, the string tensions sigma_k related to sources with Z_N charge k, using Monte Carlo sim…
Center dominance, Casimir scaling, and confinement in lattice gauge theory
L. Del Debbio, M. Faber, J. Greensite +1
We present numerical evidence that supports the theory of quark confinement based on center vortex condensation. We introduce a special gauge ("maximal center gauge") and center pr…
Chiral symmetry breaking in the 3-d Thirring model for small
L. Del Debbio
We study the dynamical breaking of chiral symmetry in the 3-d Thirring model for a small number of fermion species. The critical point is identified by fitting lattice data to an e…
Center Dominance, Center Vortices, and Confinement
L. Del Debbio, M. Faber, J. Greensite +1
We present a variety of numerical data supporting the Center Vortex theory of confinement. A method is introduced for identifying the location of center vortices, in thermalized ga…
