Gauge-invariant nonlocal quark condensates in QCD
M. D'Elia, A. Di Giacomo, E. Meggiolaro
We study, by numerical simulations on a lattice, the behaviour of the gauge-invariant nonlocal quark condensates in the QCD vacuum both in the quenched approximation and with four…
Gauge-invariant quark-antiquark nonlocal condensates in lattice QCD
M. D'Elia, A. Di Giacomo, E. Meggiolaro
We study, by numerical simulations on a lattice, the behaviour of the gauge-invariant quark-antiquark nonlocal condensates in the QCD vacuum with dynamical fermions. A determinatio…
Gauge invariant Field Strength Correlators in QCD
A. Di Giacomo, M. D'Elia, H. Panagopoulos +1
Gauge invariant correlators in QCD are studied on the lattice.A Systematic determination of the correlation lengths for gluon field strength correlators and quark correlators is ma…
Field strength correlators in QCD: new fits to the lattice data
Enrico Meggiolaro
We discuss the results obtained by fitting the lattice data of the gauge-invariant field strength correlators in QCD with some particular functions which are commonly used in the l…
The topological susceptibility of QCD: from Minkowskian to Euclidean theory
Enrico Meggiolaro
We show how the topological susceptibility in the Minkowskian theory of QCD is related to the corresponding quantity in the Euclidean theory, which is measured on the lattice. We d…
