Resumo

"One of the cornerstones of the Standard Model of particle physics and of general relativity is Lorentz symmetry. It was first tested experimentally already in 1887 by Michelson and Morley. Since the 1990's there has been a revival of interest in experimental tests due, in particular, to the fact that the majority of theoretical approaches to quantum gravity can accommodate small deviations from Lorentz symmetry. is talk will start with a brief review of how Lorentz symmetry could be broken in some of these theories. en it is shown that a natural, systematic way to parametrize small deviations from Lorentz symmetry is by using an effective field theory, the so-called Standard-Model Extension. Finally some recent experiments and observational bounds are discussed."
