FCNC, CP violation and implications for some rare decays in an SU(4)_L X U(1)_X extension of the standard model
Alejandro Jaramillo, Luis A. Sanchez
Extensions of the standard model (SM) with gauge symmetry SU(3)_c X SU(4)_L X U(1)_X (3-4-1 extensions) where anomaly cancellation takes place between the fermion families (three-f…
Phenomenology of a three-family model with gauge symmetry SU(3)_c X SU(4)_L X U(1)_X
Stiven Villada, Luis A. Sanchez
We study an extension of the gauge group SU(3)_c X SU(2)_L X U(1)_Y of the standard model to the symmetry group SU(3)_c X SU(4)_L X U(1)_X (3-4-1 for short). This extension provide…
Effects of quark family nonuniversality in SU(3)_c X SU(4)_L X U(1)_x models
Jorge L. Nisperuza, Luis A. Sanchez
Flavour changing neutral currents arise in the extension of the standard model because anomaly cancellation among the fermion families requir…
Stability of the Scalar Potential and Symmetry Breaking in the Economical 3-3-1 Model
Yithsbey Giraldo, William A. Ponce, Luis A. Sánchez
A detailed study of the criteria for stability of the scalar potential and the proper electroweak symmetry breaking pattern in the economical 3-3-1 model, is presented. For the ana…
SU(4)_L X U(1)_X three-family model for the electroweak interaction
Luis A. Sanchez, Luis A. Wills-Toro, Jorge I. Zuluaga
An extension of the gauge group of the standard model to the symmetry group (3-4-1 for short) is presented. The model does not conta…
Systematic study of the SU(3)_c X SU(4)_L X U(1)_X gauge symmetry
William A. Ponce, Luis A. Sanchez
We carry a systematic study of possible extensions of the standard model based on the gauge group SU(3)_c X SU(4)_L X U(1)_X. We consider both models with particles with exotic ele…
