Expansão do Universo e geração de massa para as partículas elementares. 2019. 37f. TCC (Graduação em Física Bacharelado) - Departamento de Física Teórica e Experimental, Universidade Federal do Rio Grande do Norte, Natal, 2019.https://repositorio.ufrn.br/handle/123456789/40232The Higgs mechanism is essential in the construction of the Standard Model to explain the origin of the elementary particles masses of the model. We will provide a historical context to the spontaneous symmetry breaking in an expanding Universe to approach the Higgs mechanism in a pedagogical way. In sequence, we will show a relation between symmetry and electrical current conservation through the study of the abelian and non-abelian gauge theories. Finally, we will introduce a spontaneous symmetry breaking that will guide to the Standard Model of Electroweak Interactions scenario, which is based on the SU (2) L ⊗ U (1) Y symmetry, generating mass to the gauge bosons and the fermions.Attribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Mecanismo de HiggsModelo PadrãoQuebra Espontânea de SimetriaPartículas ElementaresHiggs MechanismStandard ModelSpontaneous Symmetry BreakingElementary ParticlesbachelorThesis
