Summary: | The effective field theories are the best tool to describe that behavior at low energy of a theory known, for example the Quantum Chromodynamics (QCD), but the greater difficulty of these theories is its renormalization. It is necessary doing it order by order in the energy expansion. We renormalizate the effective field theory that describe the QCD at low energies until order p4. By means the technique the background field method are obtained the twelve constant that appear in the effective lagrangian. Obtaining the renormalizate effective theory of QCD until order p4. |
