3–3–1 models at electroweak scale

AbstractWe show that in 3–3–1 models there exist a natural relation among the SU(3)L coupling constant g, the electroweak mixing angle θW, the mass of the W, and one of the vacuum expectation values, which implies that those models can be realized at low energy scales and, in particular, even at the electroweak scale. So that, being that symmetries realized in Nature, new physics may be really just around the corner
