# Bilepton effects on the WWV* vertex in the 331 model with right-handed neutrinos via a SU{sub L}(2)xU{sub Y}(1) covariant quantization scheme

## Abstract

In a recent paper [J. Montano, F. Ramirez-Zavaleta, G. Tavares-Velasco, and J. J. Toscano, Phys. Rev. D 72, 055023 (2005).], we investigated the effects of the massive charged gauge bosons (bileptons) predicted by the minimal 331 model on the off-shell vertex WWV* (V={gamma}, Z) using a SU{sub L}(2)xU{sub Y}(1) covariant gauge-fixing term for the bileptons. We proceed along the same lines and calculate the effects of the gauge bosons predicted by the 331 model with right-handed neutrinos. It is found that the bilepton effects on the WWV* vertex are of the same order of magnitude as those arising from the standard model and several of its extensions, provided that the bilepton mass is of the order of a few hundred of GeVs. For heavier bileptons, their effects on the WWV* vertex are negligible. The behavior of the form factors at high energies is also discussed as it is a reflection of the gauge invariance and gauge independence of the WWV* Green function obtained via our quantization method.
