Quantum Chromodynamics (QCD) is believed to be the theory of strong
interactions. At high energies, it has been successfully applied to explain
the interactions in accelerators. At these energies, the method used to do
the calculations is perturbation theory. But at low energies, since the
strong coupling constant becomes large, perturbation theory is no longer
applicable. Hence, one needs non-perturbative approaches. Some of these
approaches are based on the fundamental QCD Lagrangian, such as the QCD sum
rules or lattice calculations. Some others use an effective theory approach
to relate experimental observables one to the other. Chiral Perturbation
Theory (ChPT) is one of these approaches. In this thesis, we make a review of chiral
perturbation theory and its applications to study the mixing phenomenon
between the neutral pseudoscalar mesons eta and eta-prime.
