Abstract
En este trabajo se estudia el proceso e+e− → U++U−− con el objetivo de analizar la producción del bosón U±±. El estudio se realiza en e lmarco de una extensión electrodébil del Modelo Estándar basada en el grupo de simetría gauge SU(3)C ⊗ SU(3)L ⊗ U(1)N en presencia de leptones pesados. Para ello, se desarrolla una versión simplificada del lagrangiano del modelo 3-3-1HL, que incluye únicamente los leptones y bosones, a fin de derivar las reglas de Feynman para el proceso de producción e+e− → U++U−−. A partir de este desarrollo, se calcula la sección eficaz total del proceso. Analizamos la dependencia de la sección de choque en función de la masa de los bosones exóticos doblemente cargados U±±, recordando que las masas de este bosón son predichas por el modelo 3-3-1
Abstract In this work, we study the process e+e− → U++U−− with the aim of analyzing the production of the U±± boson. The study is conducted within the framework of an electroweak extension of the Standard Model based on the gauge symmetry group SU (3)C ⊗ SU (3)L ⊗ U (1)N in the presence of heavy leptons. To this end, a simplified version of the 3-3-1HL model Lagrangian is developed, which includes only leptons and bosons, in order to derive the Feynman rules for the production process e+e− → U++U−−. Based on this development, the total cross section of the process is calculated. We analyze the dependence of the cross section as a function of the mass of thedoubly charged exotic bosons U±±, noting that the masses of this boson are predicted by the 3-3-1 model.
