We consider an extension of the Standard Model in which the symmetry is enlarged by a global flavour factor A 4 and the scalar sector accounts for three copies of the Standard Model Higgs, transforming as a triplet of A 4. In this context, we study the most general scalar potential and its minima, performing for each of them a model independent analysis on the related phenomenology. We study the scalar spectrum, the new contributions to the oblique corrections, the decays of the Z and W ±, the new sources of CP and flavour violation, which all are affected by the introduction of multiple Higgses transforming under A 4. We find that this model independent approach discriminates the different minima allowed by the scalar potential.
