Remarks on the U(1) axial symmetry in QCD at zero and non-zero temperature
Enrico Meggiolaro
This paper is organized in two parts. The first part (Sections 2-5) is dedicated to the theory at T=0 and contains a pedagogical review of some fundamental aspects related with the…
Gauge-invariant field-strength correlators in pure Yang-Mills and full QCD at finite temperature
M. D'Elia, A. Di Giacomo, E. Meggiolaro
We study by numerical simulations on a lattice the behaviour of the gauge-invariant two-point correlation functions of the gauge-field strengths across the deconfinement phase tran…
The U(1) axial symmetry and the chiral transition in QCD
Enrico Meggiolaro
We discuss the role of the U(1) axial symmetry for the phase structure of QCD at finite temperature. We expect that, above a certain critical temperature, also the U(1) axial symme…
On the dependence of the gauge-invariant field-strength correlators in QCD on the shape of the Schwinger string
A. Di Giacomo, E. Meggiolaro
We study, by numerical simulations on a lattice, the dependence of the gauge-invariant two-point field-strength correlators in QCD on the path used to perform the color parallel tr…
