Improved lattice operators: the case of the topological charge density
C. Christou, A. Di Giacomo, H. Panagopoulos +1
We analyze the properties of a class of improved lattice topological charge density operators, constructed by a smearing-like procedure. By optimizing the choice of the parameters…
Topological aspects of QCD
A. Di Giacomo
We review recent results from lattice on topological aspects of QCD: most of the results refer to monopoles and to instantons. We discuss in detail the evidence for condensation of…
Improving the topological charge density operator on the lattice
C. Christou, A. Di Giacomo, H. Panagopoulos +1
We analyze the properties of a class of improved lattice topological charge density operators, constructed by a smearing-like procedure. By optimizing the choice of the parameters…
Colour confinement as dual Meissner effect: gauge theory
L. Del Debbio, A. Di Giacomo, G. Paffuti +1
We demonstrate that confinement in gauge theory is produced by dual superconductivity of the vacuum. We show that for (temperature of deconfining phase transition…
Monopole Condensation in Gauge Theory Vacuum
Adriano di Giacomo
The condensation of monopoles (dual superconductivity) of QCD vacuum is reviewed. Direct evidence is produced that the system, in the confined phase, is a dual superconductor.
Topological charge density renormalization in the presence of dynamical fermions
B. Alles, A. Di Giacomo, H. Panagopoulos +1
We study the renormalization group behaviour of the topological charge density in full QCD on the lattice. We propose a way of extracting the necessary renormalization functions fr…
