In this thesis we have investigated the enlargement of the gauge group of the Standard Model of particle physics; in particular, we have considered two New Physics models: a model with gauged flavour and a 331 model. First we have built the theory of the models, from the basic principles to the Feynman rules. Then we have examined the phenomenology, focusing on the flavour sector of quarks: we have analytically calculated the effects on the processes containing Flavour-Changing Neutral Currents and performed a numerical analysis. We have obtained predictions that can be compared with the LHC experimental data in the next future, in order to provide definitive statements about the considered models.
