Estudo da gravidade Rainbow e aplicações em teoria de espalhamento.

Abstract

In this dissertation, we consider Rainbow gravity to be an appropriate model for studying the Schwarzschild Universe in the high energy regime. Given this, the temporal sector of the metric is modiĄed in such a way as to establish a peculiar scenario to verify the implications on the properties of the scattering theory. Our studies revolve around the idea that Rainbow functions are capable of affecting the differential and absorption cross sections, thus generating structures dependent of a parameter that controls the Lorentz invariance violation at high-energy.
