Abstract

Based on the expectation generated by the discovery of new particles by current colliders, we analyze the decay of the Z' boson in the frame of one of the SU(3)L \otimes U(1)N electroweak extensions of the standard model. The main objective is calculate the decay rate of this exotic boson in the aforementioned model at the tree level. With this purpose we need to develop the gauge sector, where we find thirty-three interaction terms. Mentioned particle (Z') has not yet been observed experimentally, but a large number of models predict its existence. This boson exhibits a variety of decay channels, but we will concentrate on the bosonic sector, in particular in the new charged vector bosons V \pm and doubly charged U \pm\pm as final products, because these are special features of the model. On the other hand, we would like to remark that this model does not account for the Z' W W vertex although this decay channel is considered one of the main ways to detect the Z' boson in the Tevatron.
