dc.descriptionEn el presente trabajo se muestra la fenomenología de las corrientes neutras que cambian sabor mediadas por escalares y por bosones vectoriales en un modelo compacto con simetría Gauge 3-4-1. De igual forma, se construyeron las corrientes físicas del modelo, para predecir de manera coherente, los valores de las cargas eléctricas de las partículas del modelo. Por último, se contrastaron las predicciones de los observables con los datos experimentales de los sistemas de mesones neutros, situación que ameritó la idea de aumentar la escala de energía, sí se deseaba dar cuenta de manera exitosa, de los datos experimentales.
dc.description.abstractWe have been studied the phenomenological implications of the 3-4-1 extension of the Standard Model. Although there was a previous work of one specific extension, we concerned about scalar mediated flavor changing neutral currents as the mean issue. We could build other physical currents, such as electromagnetic, and neutral ones as well. With these constructions we were able to compare the predictions of the model with experimental results of neutral mesons systems and elicit conclusions. One thing we found was, it must be necessary arise de value of the scale of symmetry breakdown, to explain experimental results.
