Este trabalho descreve os métodos e os resultados encontrados a partir da implementação de métodos estáticos para análise da estabilidade de tensão em sistemas elétricos de potência. A determinação da margem de estabilidade de tensão foi

A sign change in the Higgs couplings to fermions and massive gauge bosons is still allowed in the framework of two-Higgs doublet models (2HDM). In this work we discuss the possible sign changes in the Higgs couplings to fermions and gauge bosons, whi

Este trabalho está dividido em duas partes distintas que constituem contribuições inéditas ao estudo da estabilidade em sistemas elétricos de potência. A primeira parte do trabalho é a mais importante e trata do problema da identificação das
We analyse the possibility that, in two Higgs doublet models, one or more of the Higgs couplings to fermions or to gauge bosons change sign, relative to the respective Higgs Standard Model couplings. Possible sign changes in the coupling of a neutral

We confront the most common CP-conserving 2HDM with the LHC data analysed so far while taking into account all previously available experimental data. A special allowed corner of the parameter space is analysed - the so-called wrong-sign scenario whe

The best limit on the strong FCNC anomalous couplings was obtained using the direct top production process at the Large Hadron Collider by the ATLAS collaboration. We perform a similar analysis but using a next-to-leading order generator, MEtop. We t

The main production mode for a light charged Higgs boson at the LHC is $pp \to t \bar t$, with one the top-quarks decaying to a charged Higgs and a $b$-quark. However, single top production also gives rise to final states with charged Higgs bosons. I

We discuss the discovery potential of a charged Higgs boson in the single top mode. The models discussed include a CP-conserving and a CP-violating version of the softly broken $Z_2$ symmetric 2HDM potential. We conclude that the single top mode coul

We show that a light charged Higgs boson signal via $\tau^\pm\nu$ decay can be established at the Large Hadron Collider (LHC) also in the case of single top production. This process complements searches for the same signal in the case of charged Higg
