Attività di ricerca
Currently doing research on the non-perturbative regime of QCD. The main objective is to formulate a non-ordinary 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.
