| dc.description.abstract | The Standard Model (SM) is the theoretical framework that describes the elementary particles and the fundamental interactions that govern them. Among the particles described by the model are neutrinos, whose interaction with the rest of the particles occurs exclusively through the weak interaction. In its original formulation, the SM assumes that neutrinos do not possess a right-handed chiral component and, therefore, predicts them to be massless particles. However, the study of the solar neutrino problem revealed that neutrinos have the property of oscillating between different flavors as they propagate. This phenomenon is only possible if neutrinos have mass, which constitutes clear evidence of physics beyond the Standard Model. Following this discovery, several mechanisms were proposed to explain the origin of neutrino masses. One of the most well-known is the Type-I seesaw mechanism, which introduces very heavy right-handed neutrinos. In this scenario, the smallness of the light neutrino masses is explained by the presence of a very high mass scale associated with these new states. As an alternative, radiative models have been proposed, in which neutrino masses are generated through loop corrections. In these models, the mass term is forbidden at tree level and appears only at the loop level, so that the smallness of neutrino masses is naturally explained by the suppression factors associated with these radiative corrections. In this work, we focus on a particular radiative model known as the Cocktail model and introduce modular flavor symmetries to explain the structure observed in the leptonic mixing parameters. In particular, we study seesaw scenarios under a non-holomorphic modular symmetry A4, while for the Cocktail model we explore a non-holomorphic modular symmetry S3. For the seesaw scenario, we are able to fit the leptonic observables within 3σ. For the Cocktail model, we also obtain a 3σ fit of the observables; however, we were not able to find solutions compatible with all the constraints from charged lepton flavor violation (CLFV), and therefore the search for a fully consistent solution remains an open problem. | en_US |
