Resumo
Neste trabalho, propomos duas extensões multi-Higgs do modelo padrão com simetrias discretas abelianas e não abelianas e com o setor escalar que possui pelo menos um dubleto de Higgs para cada férmion do MP. Mostramos que do ponto de vista fenomenológico os modelos concordão com os dados experimentais e as massas e as matrizes de mistura CKM e PMNS são corretamente obtidas, para o primeiro modelo que descreve o setor dos quarks e dos léptons e para o segundo modelo, que descreve somente o setor dos léptons a matriz de mistura PMNS e as massas são devidamente obtidas
In this work we propose two multi-Higgs extension of the Standard Model with Abelian and non Abelian discrete symmetries and a scalar sector which has at least one Higgs doublet for each fermion of the Standard Model. From the phenomenological point of view the models are safe and the masses and the mixing matrices CKM and PMNS are properly obtained for the first model that describes the sector of quarks and leptons. The second model describes only the leptonic sector, but the mixing matrix and masses are also obtained in compliance with the experimental data
