| dc.description | En esta tesis se realizó el cálculo de la polarización del vacío en electrodinámica cuántica al primer orden perturbativo (un-loop) utilizando dos métodos. El método diagramático basado en las reglas de Feynman y el método de unitariedad de Cutkosky asociado con el teorema óptico en teoría cuántica de campos. En el primer procedimiento fue necesario aplicar la regularización dimensional para remover las divergencias ultravioletas presentes en la amplitud del observable físico, mientras que con la segunda prescripción se utilizaron las reglas de Cutkosky donde se evitan dichas discontinuidades y se calcula la parte imaginaría de la amplitud, la cual posteriormente se utiliza para hallar la amplitud completa a partir de las relaciones de dispersión derivadas de los teoremas integrales del análisis complejo. Además, se implementó un código en el lenguaje de Wolfram Mathematica, con ayuda de los paquetes FeynArts y FeynCalc, que permitieron obtener una expresión para la polarización del vacío equivalente a la encontrada con los dos métodos analíticos. | es_CO |
