1. Lattice QCD: a nonperturbative study in the Feynman Gauge / QCD na rede: um estudo não-perturbativo no calibre de Feynman
The infrared behavior of gluon and ghost propagators is of fundamental importance for the understanding of the low-energy limit of quantum chromodynamics (QCD), especially with respect to the problem of the confinement of quarks and gluons. The goal of this thesis is to implement a new method to study the gluon propagator in the linear covariant gauge in lat

2. A local non-Abelian gauge invariant action stemming from the nonlocal operator FmuN(D²)-1FmuN
We report on the nonlocal gauge invariant operator of dimension two, FµN (D²)-1 FµN. We are able to localize this operator by introducing a suitable set of (anti)commuting antisymmetric tensor fields. Starting from this, we succeed in constructing a local gauge invariant action containing a mass parameter, and we prove the renormalizability to all orders
