Abstract in Portuguese
Nesta tese, investigamos diversos tópicos atuais e relevantes em física de neutrinos. Contribuimos com a análise da determinação do menor ângulo de mistura leptônico, ômega 13, e estudamos, de maneira probabilística, o impacto decorrente na matriz de massa dos neutrinos. Tendo em vista o último parâmetro de oscilação desconhecido, a fase de violação de CP, estudamos uma medida apropriada para experimentos como T2K e NOvA, chamada fração de exclusão de CP. Além disso, analisamos as antigas e recentes anomalias dos experimentos de oscilação de neutrinos em curtas distâncias, realizando o mais completo e detalhado ajuste global até o presente momento.

Abstract in English
In this thesis, we investigate several recent and relevant topics in neutrino physics. We have contributed to the analysis of the smallest mixing angle, omega13, and we have studied, in a probabilistic fashion, the consequent impact in the neutrinos mass matrix. In view of the last unknown oscillation parameter, the CP violation phase, we study an appropriate measure for experiments like T2K and NOvA, the CP exclusion fraction. Besides, we analyses the recent and older anomalies of short baseline neutrino oscillation experiments, performing the most complete and detailed global fit up to date.
