Abstract in Portuguese
O objetivo deste projeto é analisar a natureza do bóson de Higgs, a saber, se ele pertence a um dubleto de SU(2)L como no modelo padrão, ou se o Higgs é um singleto desta simetria, o que ocorre, por exemplo, em modelos de quebra dinâmica de simetria. Utilizando os dados experimentais disponíveis, analisaremos os acoplamentos do Higgs com bósons vetoriais, bem como os acoplamentos tríplices de gauge, para testar a natureza do bóson de Higgs.

Abstract in English
The goal of this project is to study the nature of the Higgs boson, that is, to verify whether the Higgs boson belongs to a SU(2)L, as in the Standard Model, or whether it is a singlet under this symmetry, as predicted by dynamical symmetry breaking models. Using the available experimental data, we analyze the Higgs couplings to gauge bosons as well as triple gauge boson couplings in order to test the nature of the Higgs.
