Resumo: | With the recent findings from ATLAS and CMS, at the LHC, of the Higgs boson and also the increasingly precise results on neutrino oscilations, the search for Beyond the Standard Model models that are consistent with this measures have been intensified. We analised the results of such searches for a few of these models. Using the 2HDM, MSSM and RSUSY3-3-1, we concluded that it is possible to obtain a Higgs boson compatible with the experiments. We also looked for a model that could have a scalar sector light enough as to escape some bounds on their masses, this regime we name Alignment Without Decoupling, and concluded that the NUHM, Non Universal Higgs masses, is capable to align the lightest scalar to the standard Higgs boson with tan 10 and still keep mA around 300 GeV. We also presented a 3-3-1 model with right-handed neutrino as a perfect framework for the Inverse Seesaw Mechanism, where it is possible to settle all the necessary particles in a natural manner and still obtain an explanation to the smallness of μ. All these models show the huge effort that is being made nowadays to obtain information and paths that can lead us to a better understanding of the Universe. |
