Each model build-up on 331 symmetry has its own interesting properties according to the representations of the gauge group used for the fermionic spectrum, that is, the main reason to explore and identify the possible sources of flavor changing neutral currents and lepton flavor violation at tree level.application/pdfAtribución-NoComercial-CompartirIgual 2.5 Colombiahttp://creativecommons.org/licenses/by-nc-sa/2.5/co/Gauge symmetryFermionic spectrumSourceshttps://doi.org/10.1155/2012/657582Generación de Nuevo Conocimiento: Artículos publicados en revistas especializadas - Electrónicos
