dc.description.abstractSe realiza un análisis fenomenológico en el marco de dos extensiones abelianas del grupo del Modelo Estándar de partículas elementales, uno universal en las familias de leptones y el otro no universal que distingue estas familias. En particular, en este trabajo se propone una extensión del modelo universal con violación CP espontánea, lo que resulta en un modelo viable que permite ajustar las cotas experimentales del momento magnético anómalo del muón y del momento dipolar eléctrico del electrón, encontrando regiones del espacio de parámetros simultáneamente compatibles con estas dos observaciones. Dentro del marco del modelo no universal leptónico, se hace un estudio detallado para el cálculo del decaimiento del mesón B en estados finales leptónicos, encontrando soluciones que se ajustan a las desviaciones encontradas en el experimento CERN-LHCb.

dc.description.abstractWe perform a phenomenological study of two abelian extensions of the Standard Model of particles, one of them being universal in the lepton families, and the other one being nonuniversal. In particular, in this work we propose a new extension of the universal model that includes spontaneous CP violation, which allow us to simultaneously fit the experimental observations of the anomalous magnetic moment of the muon and the electric moment of the electron. On the other hand, through the non-universal model, we carry out a detailed study of the decay of the B meson into leptons. As a result, we find solutions that fits the deviations found at the CERN-LHCb collaboration.eng
