| dc.description.abstract | Several models of inflationary cosmology have been recently established. They provide a wide and rich field of research where most of the predictions are meant to be tested within the next generation of cosmological experiments. However, on this talk we place particular interest on the effective theory of inflation because it (effectively) incorporates the vast majority of these models in one general Lagrangian. Such Lagrangian synthesizes the relevant physics of inflation at some energy scale of interest; however, to develop such effective theory of inflation one has to assume a priori the symmetries of space-time. This elucidates the fact that when we step forward to determine the reasons or meaning underlying the physical principles, we often find that everything points towards symmetries. One other way to construct an effective action is by considering a UV-complete theory and integrate out the heavy degrees of freedom that are not manifest at some desired energy scale. Evidently, some of the symmetries of the complete theory will not necessarily be symmetries of the effective description. In this sense, the physics of a process that occurs at some energy scale may be derived from a more general (elegant?) view of Nature. For this, and other several reasons, it is convenient to consider Supersymmetry as a fundamental extension of the Poincaré group which represents the symmetries of space-time. The question to be worked out during this talk is whether these two effective prescriptions are equivalent in the context of spontaneously broken Supergravity and inflation. | spa |
