Description
The Standard Model (SM) of particle physics describes three of the four fundamental forces in nature: electromagnetic (EM), weak, and strong interaction. Besides its theoretical elegance, the SM provides a unified framework to explain a plethora of natural phenomena, leading to predictions that stand up to rigorous experimental testing. Nonetheless, some questions remain unanswered within this standard theory.
In my presentation, I will address neutrino oscillations by considering effective neutrino masses described by the Weinberg operator. I will also explore the longstanding flavour puzzle, i.e., the lack of a unique guiding principle to explain the observed fermion masses and mixing patterns. A popular approach to tackling this matter involves requiring some elements in lepton and quark mass matrices to vanish by imposing Abelian flavour symmetries. However, as the SM does not allow the implementation of this approach, I focus on one of its simplest extensions: the two-Higgs-doublet model (2HDM).
