Screened massive expansion of the quark propagator in the Landau gauge
Giorgio Comitini, Daniele Rizzo, Massimiliano Battello +1
The infrared behavior of the quark propagator is studied at one loop and in the Landau gauge () using the screened massive expansion of full QCD and three different resummatio…
Thermal extension of the screened massive expansion in the Landau gauge
Fabio Siringo, Giorgio Comitini
The massive screened expansion for pure SU(3) Yang-Mills theory is extended to finite temperature in the Landau gauge. All thermal integrals are evaluated analytically up to an ext…
Perturbation theory of non-perturbative Yang-Mills theory: a massive expansion from first principles
Giorgio Comitini
The main objective of this thesis is to present a new analytical framework for low-energy QCD that goes under the name of massive, or "screened", perturbative expansion. The massiv…
Mass generation and deconfinement in pure Yang-Mills theory: a variational study
Giorgio Comitini
A simple variational argument based on the Gaussian Effective Potential (GEP) is put forward to give evidence for mass generation and deconfinement in pure Yang-Mills SU(N) theory.…
