Self-couplings of gauge bosons in 3-4-1 models

Abstract

Feynman rules for self-couplings of the gauge bosons in the general 3-4-1 model based on the gauge group $SU(3)_c\otimes SU(4)_L \otimes U(1)_X$ will be presented in this work. The results are checked to be consistent with previous works. The results also confirm important relations between different triple and quartic gauge couplings assumed previously for constructing general one-loop contributions to physical processes searched by experiments.
