Abstract

We discuss the most relevant features of a BSM model with extra gauge symmetry, the so called 331 model. The gauge group is SU(3)_c× SU(3)_L × U(1)_X impling the presence of extra gauge bosons, both charged and neutral, as well as extra/exotic fermions and an enlarged scalar sector. We present the relevant phenomenology of doubly-charged gauge bosons, which are a distinctive feature of a version of the 331 model, and discuss the role of BSM phenomenology as a tool for testing GUT (inspired) theories.
