Matriz de mezcla de neutrinos en el marco de la simetría μ−τ de reflexión.

Abstract

Neutrino oscillations provided the rst direct evidence of physics beyond the Standard Model, thus demonstrating neutrino mixing. The experimental determination of the oscillation parameters suggests the existence of a symmetry present in the mixing matrix known as μ−τ symmetry. This research work focuses on the study of μ − τ re ection symmetry and the possible implications of its deviation on the oscillation parameters. Under the approximation of small deviations, it was determined that the Majorana phases are strongly correlated, and the implication of this correlation in the parameter space for the e ective Majorana mass is shown. This information is important in the construction of models for the generation of neutrino masses and mixings, including CP-violating phases.
