In this thesis, we focus on analyzing the different ways in which new physics scenarios, such as Violation of the Equivalence Principle (VEP) and Quantum Decoherence, can manifest themselves in the context of the neutrino oscillation phenomenon. Within the framework of the DUNE experiment, we examine several effects of the VEP, such as the possibility of getting a misconstructed neutrino oscillation parameter region provoked by our ignorance of VEP in nature, as well as the impact on the DUNE sensitivity for CPV and mass hierarchy. Additionally, we set limits for the different textures of the gravitational matrix and the diverse scenarios of energy dependencies associated with the Lorentz Violation. On the other hand, we demonstrate that the quantum decoherence phenomenon applied to the neutrino system leads us to fascinating phenomenological scenarios. One of the scenarios analyzed, wit...

In our study, the cathodic material xLi2MnO3–(1−x)LiNi0.5Mn0.5O2 was synthesized by means of the co-precipitation technique. The effect of x (proportion of components Li2MnO3 and LiNi0.5Mn0.5O2 ) on the structural, morphological, and electrochemical performance of the material was evaluated. Materials were structurally characterized using X-ray diffraction (XRD), and the morphological analysis was performed using the scanning electron microscopy (SEM) technique, while charge–discharge curves and differential capacity and impedance spectroscopy (EIS) were used to study the electrochemical behavior. The results confirm the formation of the structures with two phases corresponding to the rhombohedral space group R3m and the monoclinic space group C2/m, which was associated to the components of the layered material. Very dense agglomerations of particles between 10 and 20 µm were also...

Desde que los neutrinos fueron propuestos por Pauli, su masa ha sido un tema de intensa investigacio´n experimental y teo´rica. Estos fueron postulados como partículas sin masa debido a la no existencia de neutrinos de mano derecha . Ahora ya probada la existencia de la masa de los neutrinos, nos vemos motivados a investigar los distintos modos por los cuales esta se puede generar. En este trabajo, se hace una revisio´n de la naturaleza del neu- trino (Dirac y Majorana) y sus diferentes mecanismos de generacio´n de masa, tales como los mecanismos seesaw. Estos mecanismos no so- lo explican la masa del neutrino si no tambi´en su pequen˜o valor en comparacio´n con los quarks y leptones cargados. Se revisa el mode- lo seesaw ma´s simple (Tipo I) donde se expande el sector fermi´onico planteando que las componentes quirales no observadas son neutrinos derechos que poseen una masa m...
