Orientador: Dr. Farinaldo da Silva Queiroz. 2023. 74f. Dissertação (Mestrado em Física) - Centro de Ciências Exatas e da Terra, Universidade Federal do Rio Grande do Norte, Natal, 2023.https://repositorio.ufrn.br/handle/123456789/57190The Standard Model of Particle Physics (SM) constitutes a successful theoretical framework that gathers all the current knowledge about the fundamental interactions of nature (except gravity) and the matter that surrounds us. Its success is due to numerous theoretical predictions that were subsequently experimentally confirmed. This dissertation thoroughly examines each of the essential elements for its understanding, as well as the need to expand its boundaries to account for phenomena still unexplained, particularly the enigma of dark matter, the nature of which is unknown.Acesso AbertoFísicaStandard modelGauge invarianceHiggs mechanismElectroweak unificationmasterThesisCNPQ::CIENCIAS EXATAS E DA TERRA::FISICA
