Abstract

In this project, it will be studied the demonstration the impossibility of a spontaneous breaking of a gauge symmetry. To achieve this it is first necessary to study path integrals, and then the techniques of field the oryon the lattice, which itself requires a considerable effort. It will also be seen the explicit gauge fixation technique in dryer to circumvent the problem of the impossibility of spontaneous broken go a gauge symmetry.
