This Ph.D. thesis presents a study of the Gribov-Zwanziger framework: from
propagators to glueballs. The chapters 2 and 3 are meant as an introduction and
only require a basic knowledge of quantum field theory. Chapter 2 explains the
techniques behind algebraic renormalization, which shall be widely used
throughout this thesis, while chapter 3 tries to give a pedagogic overview of
the Gribov-Zwanziger framework as this is not available yet in the literature.
The subsequent chapters contain own research. First in chapter 4, we shall dig
a bit deeper in the Gribov-Zwanziger framework, by exploring the BRST symmetry
and the KO criterium. Next, in chapter 5 we shall elaborate on the ghost and
the gluon propagator in the infrared and present a refined Gribov-Zwanziger
action. Further, we present two chapters on the search for physical operators
within the (refined) Gribov-Zwanziger framework, chapter 6 and 7. A small
chapter 8 is devoted to some values for different glueballs. We end this thesis
with the conclusions, chapter 9.Comment: 326 pages, Thesis submitted in fulfillment of the requirements for
