Abstract
Conceive a renormalizable quantum theory of gravitation and understand the phase transition associated with confinement are two of the greatest challenges in modern physics. The basic objective of this research project aims to obtain some results, which may be useful for a better understanding of certain aspects involved in these problems.A fundamental theory of gravitation could eventual…

Abstract
We will investigate certain physical properties of field theories at finite temperature using the background field method to obtain the effective action of static gauge fields interacting with thermal particles, in the high temperature limit. First, we intend to calculate the high temperature limit of the effective action of the static Maxwell field interacting with a QED plasma, at two …

Abstract
Quantum Chromodynamics (QCD) today is the well-established theory of strong interactions, characterized by a renormalizable non-Abelian gauge field theory with the color group SU(3). The coupling constant in QCD varies with energy scale, exhibiting asymptotic freedom at high energy scales. However, at lower energy scales, the coupling constant increases, leading to the breakdown of pertur…
