Abstract

The main goal of the project is the study of the effects of due to the inclusion of mesonic fluctuations in the description of the phase diagram of QCD in the presence of an external magnetic field. Special attention will be given to the regularization of the theory, since practically all recent results in the literature indicate that the correct separation of the divergences play a fundamental role in the phase structure of the system. Confinement effects will be simulated by the inclusion of the Polyakov loop potential in the Lagrangean of the Nambu-Jona-Lasinio model, and the mesonic fluctuations through the self-energy computed in lowest 1/Nc order.
