Behaviour of the topological susceptibility across the deconfining phase transition
Di Giacomo, A.; Meggiolaro, E.; Panagopoulos, Haralambos G. (1992)We investigate the behaviour of the topological susceptibility of pure SU(2) gauge theory at the deconfining phase transition. The cooling method gives ambiguous results. The susceptibility, determined by the field theoretical ...

Field strength correlators in QCD at zero and non-zero temperature
Di Giacomo, A.; Meggiolaro, E.; Panagopoulos, Haralambos G. (1997)We study, by numerical simulations on a lattice, the behaviour of the gauge-invariant field strength correlators in QCD both at zero temperature, down to a distance of 0.1 fm, and at finite temperature, across the deconfinement ...

Gauge-invariant field strength correlations in QCD at zero and non-zero temperature
Di Giacomo, A.; Meggiolaro, E.; Panagopoulos, Haralambos G. (1997)We determine, by numerical simulations on a lattice, the gauge-invariant two-point correlation functions of the gauge field strengths in the QCD vacuum at zero temperature, down to a distance of 0.1 fm. We also study the ...

A lattice determination of the slope at q2 = 0 of the topological susceptibility in SU (3) Yang-Mills theory
Di Giacomo, A.; Meggiolaro, E.; Panagopoulos, Haralambos G. (1992)We determine the slope of the topological susceptibility at q2 = 0 by Monte Carlo simulations, for an SU(3) quenched gauge theory. The value is consistent with the phenomenological estimates, within the (large) errors. © 1992.
