Title in Portuguese
Gravitação como quebra espontânea de simetria
Keywords in Portuguese
Física de partículas
Gravitação
Simetria
Abstract in Portuguese
Estudamos duas teorias nas quais o termo de Einstein, R -9 , encontra-se ausente da lagrangeana original do problema e é gerado através de mecanismo de quebra espontânea de simetria. Na primeira delas e introduzido um campo escalar, que e o responsável pelo fenômeno de quebra de simetria. Na segunda, não há campo escalares: a quebra de simetria aparece como um efeito dinâmico.
Title in English
Gravitation as spontaneous symmetry breaking
Keywords in English

Particle physics
Symmetry
Abstract in English
We study two theories in which the Einstein term, R -9, is not present in the original lagrangian. This term is created by a spontaneous broken symmetry mechanism. In the first theory, there is a scalar field through which the breaking of symmetry occurs. In the second one, there is no scalar field. The symmetry is dynamically broken.
