“Approcci analitici alla QCD non-perturbativa e proprietà del Quark Gluon Plasma”
Currently doing research on the non-perturbative regime of QCD, both in the vacuum and at finite temperature/density. The main objective is to formulate a non-standard perturbative framework in which – in compliance with the results of lattice QCD – the gluons are allowed to develop a dynamical mass at low energies, while the IR Landau pole of ordinary perturbation theory is prevented from appearing in the running of the strong coupling constant.
