Abstract
En el presente trabajo se calculó la anchura teórica de decaimiento del bosón de Higgs H03 del Modelo 331.Este modelo, extiende el grupo de simetría electrodébil del Modelo Estándar a SU(3)L ⊗ U(1)N, introduciendo nuevas partículas exóticas que adquieren masa vía ruptura de simetría SU(3) L⊗U (1)N−vχ→ SU (2)L⊗U (1) Y . Se desarrolló los sectores de Higgs y Yu-kawa, obteniéndose el lagrangiano de interacción del bosón de Higgs H03 con otras partículas. Asimismo, se dedujeron las reglas de Feynman para las interacciones de H03 en contribuciones de primer orden. Finalmente, se calcularon las anchuras teóricas de decaimiento de H03 para todos sus posibles canales, encontrando que el canal dominante es H03→ H0 1H 01, con un branching ratio del 86.95% y 96.81% para valores de vχ de 4y5 TeV, respectivamente.
Abstract In this work, the theoretical decay width of the Higgs boson H03 within the 331 Model was calculated. This model extends the electroweak symmetry group of the Standard Model to SU (3)L ⊗U(1)N, introducing new exotic particles that acquire mass via the symmetry brea- king SU(3)L⊗U(1)N vχ−→SU(2)L⊗U(1)Y. The Higgs and Yukawa sectors were developed, obtaining the interaction Lagrangian of the Higgs boson H03 with other particles. Feynman rules for the interactions of H03 at first-order contributions were also derived. Finally, the theoretical decay widths of H03 for all possible channels were calculated, showing that the dominant channel is H03 → H01 H01, with a branching ratio of 86.95% and 96.81% for vχ values of 4 and 5 TeV, respectively.
